“This atmospheric historical thriller is as good as it gets” (Julia Spencer-Fleming, author of I Shall Not Want) in the evocative Barker and Llewelyn series as mysterious murders hint at a dark conspiracy in the heart of London.

When an Italian assassin’s body is found floating in a barrel in Victorian London’s East End, enquiry agent Cyrus Barker and his assistant Thomas Llewelyn are called in to investigate. Soon corpses begin to appear all over London, each accompanied by a Mafia Black Hand note. As Barker and Llewelyn dig deeper, they become entangled in the vendettas of rival Italian syndicates—and it is no longer clear who is a friend or foe.

From award-winning author Thomas comes the latest adventure of Victorian enquiry agent Cyrus Barker and his apprentice Thomas Llewelyn, who must save London from an invasion of the Sicilian mafia.

"Will Thomas's The Black Hand is what Conan Doyle would write after taking tea with Lee Child. The Barker & Llewelyn series transports you to the fog-shrouded, gaslit streets of Victorian London, then sweeps you away like the Thames at flood tide. This atmospheric historical thriller is as good as it gets." -- Julia Spencer-Fleming, Edgar finalist and author of I Shall Not Want
