Probationary constable Peter Grant dreams of being a detective in London's Metropolitan Police. Too bad his superior plans to assign him to the Case Progression Unit, where the biggest threat he'll face is a paper cut. But Peter's prospects change in the aftermath of a puzzling murder, when he gains exclusive information from an eyewitness who happens to be a ghost. Peter's ability to speak with the lingering dead brings him to the attention of Detective Chief Inspector Thomas Nightingale....

Dorothy Graham is dead, which is inconvenient, not least for her. Luckily, she has planned for this eventuality. Now, if any of the truly dreadful people she is related to want to get their hands on her money, they’re going to have to do so via a fiendish difficult and frankly bizarre competition of Dorothy’s devising. After all, just because you’re dead, it doesn’t mean you can’t enjoy a last laugh at the expense of people who made your life miserable.

The first time somebody tried to kill him was an accident. The second time was deliberate. Now Paul Mulchrone finds himself on the run with nobody to turn to except a nurse who has read one-too-many crime novels and a renegade copper with a penchant for violence. Together they must solve one of the most notorious crimes in Irish history. Or else they’ll be history.

Return to the world of Rivers of London in this first short-story collection from best-selling author Ben Aaronovitch. Tales from the Folly is a carefully curated collection that gathers together previously published stories and brand-new tales in the same place for the first time.

The story opens with the apparently accidental drowning of a sixth form student in the Norfolk countryside. As a matter of routine, or so it seems, the case passes across the desk of Detective Sergeant Smith, recently returned to work after an internal investigation into another case that has led to tensions between officers at Kings Lake police headquarters. As an ex-DCI, Smith could have retired by now, and it is clear that some of his superiors wish that he would do so.
