John Watson is worried for his companion when a new unexpected art case props up. Sherlock will not divulge any information, so John decides to turn to the America's finest, bringing New York's infamous Neal Caffery and Peter Burke to London and some of the finest minds known to man. This is a crossover between SHERLOCK, WHITE COLLAR and SCORPION.

Neal Caffrey is dead. Perfectly officially dead. Now the man of same appearance roam around as Albert Hardy, a French artist. His target as free man is Codex Gigas about to be displayed in London. Sherlock is put to the same case with the renowned insurance investigator Sara Ellis by his awful brother Mycroft. The two brilliant minds clash at the heart of British fine arts.

Sherlock gets roped into a favour for Mycroft, busting a smuggling ring moving state secrets out of the country through New York. He never expected he'd be working with the man who broke his heart so long ago: Neal. Sodding. Caffrey.
