Meet the Diamond Brothers, the world's worst private-detective agency, in this Chandler-esque spoof from the creator of the bestselling Alex Rider series. Life as the younger brother of the world's most defective detective can be tough - and these two adventures will test Nick to the full. What connects them? Murder! And if the Diamond Brothers don't play their cards right, they could be next.

It's a dangerous life being the brother of the world's worst private detective: but Nick Diamond has survived, so far. However his survival instincts are about to be tested to the full: a school reunion on a remote island, a holiday to Paris, an investigation into the whereabouts of a man and the visit of a world famous singer.
