London, December 1895.

Former Baker Street Irregular Tim Badger, and his detective partner Ben Watson, embark on one of their most deadly investigations yet!

Why did a magician unknowingly stab to death his assistant in the basket trick in front of a horrified audience at the celebrated Royal Canterbury Theatre? The magician, though professing his innocence, is ridiculously tight-lipped even as he languishes in a cell at Scotland Yard.

As Badger and Watson slowly pull back the layers of the conspiracy behind it, Ben must go undercover as a knife-thrower on the Canterbury's stage with the assistance of his new sweetheart, Miss Eliza Wells.

Even Sherlock Holmes and Doctor Watson join their investigation that takes Badger and Watson from the glittering stage of the music hall, to its deadly backstage secrets, through the dark underworld of the East End, and to a crime syndicate led by a familiar name…
