Ghosts and ghouls beware! London’s smallest, shabbiest, and most talented psychic detection agency is back. Life is never exactly peaceful for Lockwood & Co. Lucy and George are trying to solve the mystery of the talking skull trapped in their ghost jar, while Lockwood is desperate for an exciting new case. Things seem to be looking up when the team is called to Kensal Green Cemetery to investigate the grave of a sinister Victorian doctor.

Lockwood & Co. might be the smallest (some might say shambolic) Psychic Detection Agency in London. But its three agents - Lockwood, Lucy and George - are exceptional talents. And they get results. When an outbreak of ghostly phenomena grows to terrifying levels in Chelsea, Scotland Yard is left baffled. Even more baffling is that Lockwood & Co appear to have been excluded from the huge team of Agents investigating the Chelsea Outbreak.

A terrible crime forces Lucy to turn to Lockwood for help and sets them on the trail of dark secrets at the heart of London society. Both professionally and personally, their investigation stirs up forces they may not be able to control.... Ghouls and spectres, thrills and tension in this brand-new instalment in Jonathan Stroud's best-selling series.

After their recent adventures, the Lockwood & Co team deserve a well-earned break...so naturally they decide to risk their lives breaking into a heavily guarded crypt. A building full of unsettled souls, it's also the final resting place of Marissa Fittes, the legendary and (supposedly) long-dead ghost hunter. What they discover their will change everything. So begins a race to get to the truth behind 'the Problem' and an epic struggle against the Fittes agency.

Three years after the events of The Golem's Eye, the young magician Nathaniel is an established member of the British Government. But he faces unprecedented problems: foreign wars are going badly and Britain's enemies are mounting attacks close to London.
