Nardello & Co.:
the chain that launders responsibility

Founded in 2003 by a former federal prosecutor, Nardello & Co. is ranked Band 1 by Chambers in the United States for a sixth consecutive year and is the only investigative firm ranked Band 1 across the US, UK and Asia-Pacific in a single year. It employs former prosecutors, former DEA agents and former intelligence officers, and markets “multi-state mobile surveillance operations,” witness coordination and “activist defense.” In 2015 it was retained through Leon Black’s counsel at Paul Weiss and surveilled a woman for a week. It says it had no contact with Epstein and did not know its work product was being shared with him. This page takes that at face value — and argues it is the most revealing fact in the episode.

Nardello & Co. has not been accused of any wrongdoing, and nothing on this page suggests it acted improperly. The firm confirmed it worked on the matter for Leon Black’s legal counsel and stated that “no one at Nardello had any contact or communication with Epstein whatsoever nor did the firm know that Mr. Black’s counsel was sharing documents or other work product with Epstein.” This page takes that account at face value — and argues that it is the most revealing fact in the whole episode.

The Finding
If the firm is telling the truth, then the people doing the surveillance did not know who was reading their reports. That is not a failure in the chain. That is what the chain is for.
Nardello & Co. is Band 1 at Chambers in the US for a sixth consecutive year, the only investigative firm ranked Band 1 across the US, UK and Asia-Pacific in a single year, and 2024 Investigations Consultancy of the Year. It is staffed by former federal prosecutors, former DEA agents and former intelligence officers. This is not a shadow operation. It is the top of the market.

This archive documents an unregulated reputation trade and, on the Paul Weiss page, the same work performed inside a licensed profession. Nardello is the third version: a firm whose entire business is doing this properly.

Its founder was a federal prosecutor in the Southern District of New York. Its recent hires include a former CIA analyst who supervised counterterrorism work at the NYPD, two former DEA special agents, and two more former SDNY prosecutors. Its clients are Fortune 500 companies, governments and NGOs. It was engaged to help recover assets after the FTX bankruptcy.

And two of its marketed service lines are the ones that matter here. Its Chambers profile describes a partner leading “multi-state mobile surveillance operations” and “the coordination of witness interviews around the world.” The firm also markets “activist defense.”

The praise for that partner, published in a legal directory, reads: “our go-to person any time we need to approach a witness… has great human touch. He makes the witnesses comfortable.” That is a professional commendation, and in almost every engagement it describes something entirely benign.

In 2015 the firm was retained through Paul Weiss, acting for Leon Black, and surveilled a woman for a week. Her movements were relayed onward to Jeffrey Epstein, and transcripts of secret recordings were produced.

The firm says it did not know. And the archive has no basis to doubt it — the denial is specific, it names what the firm did and did not know, and no evidence contradicts it.

Which is precisely why this page exists. The most disturbing version of this story is not one where a firm behaved badly. It is one where every participant behaved correctly on the information available to them, and the aggregate was still a week of surveillance on a private woman, reported to a convicted sex offender.

Section 01

The Firm

2003
Founded

Dan Nardello, a former federal prosecutor in the Southern District of New York, founds the firm in London. He had observed that most investigative firms lacked the responsiveness and creativity their clients wanted. The firm’s motto: “We find out.”

Since
Who works there

Former US federal prosecutors, former general counsels, former law enforcement, and intelligence operatives. Recent hires include a former CIA analyst who later supervised counterterrorism analysts in the NYPD Intelligence Division, two former DEA special agents, and two former SDNY prosecutors.

Since
Who hires them

The world’s leading law firms and financial institutions, Fortune 500 and FTSE 100 companies, governments, NGOs, sports organisations, academic institutionsand high-net-worth individuals and family offices.

Practice
What is sold

Anti-corruption and fraud investigations, asset tracing, litigation support, digital forensics, political risk, monitorships — and two lines that matter here: “activist defense” and, per its Chambers profile, “multi-state mobile surveillance operations” together with the coordination of witness interviews around the world.

Praise
How the craft is described

Chambers respondents on the partner who leads that practice: “our go-to person any time we need to approach a witness” and “has great human touch. He makes the witnesses comfortable.” These are professional commendations, published by a legal directory.

2015
The engagement

Retained through Leon Black’s legal counsel at Paul Weiss. Per reporting on the released files, the firm surveilled a woman referred to as “GG” for a full week and produced transcripts of secret recordings. Her movements were relayed onward to Epstein.

In the files
Two memoranda

Two Nardello & Co. documents appear in the Justice Department release, both on firm letterhead and both marked “PRIVILEGED AND CONFIDENTIAL — ATTORNEY CLIENT AND WORK PRODUCT COMMUNICATION.” One of them has now been read. EFTA01190807 runs to 24 pages (EFTA01190807–830) and is a draft transcript of a secretly recorded two-hour lunch. EFTA01190807 · EFTA01200840

2026
The firm’s response

A spokesperson confirmed the firm worked on the case for Black’s legal counsel but denied working with Epstein: “In the course of that engagement, no one at Nardello had any contact or communication with Epstein whatsoever nor did the firm know that Mr. Black’s counsel was sharing documents or other work product with Epstein.”

2020–26
Standing, unchanged

Ranked Band 1 by Chambers and Partners in the United States for a sixth consecutive year, and the first and only investigative firm ranked Band 1 across the US, UK and Asia-Pacific in a single year. Named 2024 Investigations Consultancy of the Year. The firm has not been accused of any wrongdoing.

Section 02

What the Memorandum Actually Is

This page previously said the contents had not been reported. That was written from a 300-character index snippet, and it was wrong. The document is readable.

EFTA01190807 is a 24-page draft transcript of a covertly recorded conversation, dated 24 August 2015, addressed to Brad S. Karp and Lorin L. Reisner at Paul, Weiss, Rifkind, Wharton & Garrison. It records a two-hour lunch on 19 August 2015 at The Modern restaurant, 9 W 53rd Street, New York.

The header states the arrangement in one line: “The recording was made with the consent of JD.” One party consented. The woman across the table did not know she was being recorded, and did not know a transcript would be produced for a law firm. New York is a one-party-consent state. This was lawful.

The conversation is a settlement negotiation, conducted in person, with one side wired.

The man, anonymised throughout as “John Doe (JD)”, describes payments already made — “I’m going to give you a million dollars to get settled… I gave you half a million when you left and then there were three payments after that” — and discusses an investor’s visa, then a passport, then a trust, and an ongoing figure of “a million dollars a year after tax.”

Three passages are worth reading exactly.

He explains Mutually Assured Destruction to her, walking through the Soviet–American nuclear analogy, as a frame for their situation.

She says: “I think it’s dangerous for me to meet with you. It could be seen as a blackmail case.”

And he advises her against retaining a lawyer“the danger of having one too early is they try to grab on to a significant piece” — when she asks him directly, “You think I should get lawyer?” The man discouraging her had two of them receiving the transcript.

Her side of it: her visa, her son’s schooling, a year moving between hotels, “my reputation, my emotional well being” — and the question “were you aware that this is happening? That my son and me were getting attacked?”

Read Carefully

“JD” is anonymised in the document as John Doe. This archive does not assert an identification from a transcript.

What can be stated: the memorandum was addressed to Leon Black’s lawyers, and Black publicly acknowledged in 2021 paying substantial sums to a Russian model over what he described as a consensual affair.

The woman is a private individual. This archive does not name her and has made no attempt to identify her.

Nothing here contradicts Nardello’s denial. The firm produced a transcript for its client’s counsel. Where it went next is the part it says it did not know.

Where the Document Was Found

These Paul Weiss work-product memoranda are in Jeffrey Epstein’s document set. In the release they sit surrounded by his personal correspondence — his own gmail account, messages to and from Karyna Shuliak, October 2015.

That is the physical proof of transmission. The material reached him, which is why it was seized, and why it is public now.

The firm does not dispute that its work product reached Epstein. Its position is that it did not know. Both things can be true at once, and that is the whole finding of this page.

Section 03

How a Chain Launders Responsibility

Not by anyone lying. By dividing the picture so that no single party holds enough of it to be accountable for the whole.

The instruction chain

Black retained Paul Weiss. Paul Weiss retained Nardello. Nardello reported to Paul Weiss. The firm says it never knew its work product was being passed to Epstein.

If that is right, the investigators did not know who was ultimately reading their reports. Which is not a defect in the firm. It is how the chain is built.

What each link could see

The investigators saw a client instruction from a reputable law firm. The law firm saw a client with a legitimate dispute. Only at the top of the chain did anyone see the whole picture.

Every participant can act properly on the information available to them, and the aggregate can still be a week of surveillance on a private woman.

Why it launders responsibility

Not by concealment — by division. No single party holds enough of the picture to be accountable for the whole of it, and each can truthfully say they did their job correctly.

This is the same structure the archive documents in the modelling pipeline and the reputation trade. Legitimate intermediaries, each doing ordinary work, assembling into something none of them would have accepted as a single instruction.

What would have caught it

Nothing available today. No rule requires an investigations firm to be told who will receive its findings, or a subject to be told they were investigated.

A disclosure duty running down the chain — identifying every party who will see the work product — would have surfaced Epstein’s involvement at the point of engagement. No jurisdiction requires it.

The Uncomfortable Version

It would be easier if the investigators were villains. They are not, on any available evidence.

They are former prosecutors and intelligence officers running a Band 1 firm, retained by one of the most respected law firms in America, doing work they do lawfully every day for Fortune 500 clients.

And the woman was still followed for a week, recorded, and had her whereabouts reported to Jeffrey Epstein.

The archive’s recurring finding, in its most uncomfortable form: the machinery does not require bad actors. It requires only that nobody is positioned to see the whole thing, and that nobody is obliged to ask.

Section 04

Open Questions

?
What is in the two memoranda?
One is a 24-page transcript of a covertly recorded lunch, now read. The second, EFTA01200840, runs to roughly 37 pages and has not been reviewed here.
?
What was the firm told the matter was?
It says it was engaged by Black’s legal counsel. What purpose it was given, and what it was told about the subject, has not been disclosed.
?
Who authorised the recordings?
Transcripts of secret recordings appear in the reporting. Who commissioned them, and under what legal advice, is not established.
?
Was the subject ever told?
A private individual was surveilled for a week and recorded. Nothing requires that she ever be informed, and nothing indicates she was.
?
Does the firm vet the end recipient?
It says it did not know its work product was going to Epstein. Whether any investigations firm asks who else will read its reports is not addressed by any professional standard.
?
How often does this happen?
One engagement surfaced because it sat inside a seized criminal file. There is no registry of private investigative engagements anywhere.
