Protecting the Files

Privilege Against Curiosity
Police access denied
Haller orders Bosch to stop searching the files, arguing that they contain privileged client communications. He uses the transfer order and the clients’ rights to force the detectives out.
A legal defense of silence
The confrontation establishes Haller’s duty to clients even when police believe a file may identify a killer. It also makes his cooperation with Bosch conditional rather than automatic.
A Safety Exception

Controlled Disclosure
A narrow proposal
Haller asks Mary Townes Holder whether he can identify clients who threatened Vincent without giving Bosch their files. He argues that the possible danger to himself justifies limited disclosure.
Judicial permission
Holder agrees that he may vet the records and file a sealed explanation. The solution preserves some confidentiality while recognizing that the threat to Haller is not hypothetical.
Bosch’s Hidden Federal Lead

Information Held Back
The FBI calls
Bosch reveals that Vincent received several brief calls from the Bureau shortly before his death. He believes the calls may relate to a federal corruption investigation.
Mutual suspicion
Haller confirms that Vincent had no federal cases but withholds other speculation. Their exchange shows that each man controls information to protect his own investigation and position.
Haller Learns of the Bribe

Confidential Knowledge
A hidden withdrawal
Bosch tells Haller about Vincent’s unexplained hundred-thousand-dollar cash withdrawal. He asks Haller to keep the information from his staff and clients.
An ethical dilemma forming
Haller recognizes that the money may have come from Elliot’s advance, but he has no proof of its destination. He must decide how to protect himself without breaching the client relationship.
Stopping the Future Crime

Preventing Jury Tampering
The rule’s exception
Haller understands that Elliot has admitted a future crime: the planned use of a sleeper juror during deliberations. He considers whether reporting it is required or whether he can prevent it himself.
A secret investigation
He asks Cisco to investigate juror seven without explaining everything. The choice protects client confidence for the moment but puts Haller and his investigator at professional and physical risk.
