Welcome to The Black Museum. If you like The Rivers of London series, The Dresden Files, The King's Watch, The Netherweird Chronicles, The Vinyl Detectives, and Good Omens, this is for you.

"The places we are going to visit tonight are by far the most dangerous that this fair city has to offer. The streets and lanes are nasty places; a man might get lost in there and never reappear. The canals are full of bodies, and the rats grow fat on them."

Christmas is coming to Victorian London's most notorious slum, the Rookeries of St Giles. And as the snow falls, the bloody body count rises. A demonic serial killer stalks the streets, and nobody is safe.

Judas Iscariot, renowned thief-taker and scourge of London's dark and dangerous underworld, has been engaged by a mysterious old businessman turned guardian angel, who wishes to keep a promising young writer called Charles Dickens safe, as he roams the streets looking for inspiration for his novels.

But Judas is not the only one watching Dickens closely. Murderers, ferocious beasts, and the rest of the worst that the underworld has to offer want his head, or his soul - depending on who gets there first.

A mouth-watering mashup of some of literature's best-known characters, Oliver Twisted, is a festive tale like no other, featuring the world's most unusual investigator.
