If you like Good Omens, The Rivers of London series, The Netherweird Chronicles, The Dresden Files, The Vinyl Detectives, and The Kings Watch, this is for you.

Welcome to The Black Museum, Scotland Yard's secret occult magic division, and the world's most unexpected and unlikeliest hero - D.C.I, Judas Iscariot.

"They are stout of heart and run towards danger carrying only a lantern and a wooden truncheon, poor fools.

They learn too late that dark magic and death are waiting for them."

The Eastern Emigres. Sidney Street. 1910.

London's cramped and politically charged East End is a battlefield.

Secret Societies and criminal gangs wage war against each other.

But now, they have more than just knives, hammers, guns, and fire.

Now, they have something infinitely more powerful - dark magic.

Winston Churchill, the Home Secretary, turns to the Met's occult magic department-the Black Museum at Scotland Yard-and enlists Sergeant Judas Iscariot's help. However, when Churchill is removed from office, the case is suddenly and mysteriously closed.

A century later, an impossible robbery takes place at an impregnable vault in London, and on the South Coast of England, a French fishing boat runs aground. Her crew are found in the hold, bludgeoned to death with lead pipes wrapped in bandages.

D.C.I, Judas Iscariot, now The Master of the Black Museum, is called in to investigate.

But there are dark forces arrayed against him, powerful creatures who mean him ill.

Who and what is the mysterious and secretive department known only as SEC14?

And what of The School of Night and the Master of the Ravens?

Are they friends or foes, or something far more dangerous?

There are dark days ahead for Judas, but aren't they always?
