New Tricks: The Gentleman Vanishes

SYNOPSIS

The team investigates the mystery of a missing scientist, after the man's wife receives a series of e-mails from someone claiming to know what happened to him. The physics professor was last seen in 2004, on a train to Paris for a conference, and when he disappeared he was working on a potentially lucrative cold fusion project that had attracted attention from many large organisations. However, as the detectives dig deeper, a shadowy Whitehall figure warns Sandra's boss Strickland they should drop the case.
