Lucy has left Lockwood & Co. A freelance operative, she is hiring herself out to other agencies – agencies that might value her ever-improving skills.

But now Lockwood needs her help.

Penelope Fittes, leader of the well-renowned Fittes Agency wants Lockwood & Co. – and only them – to locate and remove the ‘Source’ for the legendary Brixton Cannibal.

It’s a tough assignment. Made worse by the tensions between Lucy and the other agents – even the skull is treating her like a jilted lover!

What will it take to reunite the team? Black marketeers, an informant ghost, a Spirit Cape that transports the wearer, and mysteries involving their closest rivals may just do the trick.

But not all is at it seems. And it’s not long before a shocking revelation rocks Lockwood & Co. to its very core . . .
