Initially it seems like an easy case for private investigator Gerhard Self. The prestigious private bank, Weller & Welker, are compiling their history and wish to discover the identity of their sleeping partner. This mysterious figure deposited a large sum in the early part of the 20th Century, thereby securing the bank's future.
But as Self investigates, money-laundering and murder make matters much less straightforward than they first seemed.
Once a Nazi prosecutor, now a PI in his early seventies, Gerhard Self is the driving force of this crime novel. Introspective, ironic and reflective, Self is a well-rounded character who finds himself questioning his own past as his investigations continue.
The aftermath and guilt of World War 2 are familiar themes which run through Schlink's works, most notably in The Reader. As for Gerhard Self, this looks like it's his final case, if so it's a good one to bow out on.
