Whispers Under Ground
Whispers Under Ground is the third novel in the Peter Grant series by English author Ben Aaronovitch, published 2012 by Gollancz. Peter Grant of Metropolitan Police department in charge of magical crimes (AKA The Folly) is called in to assist in a murder investigation. The victim, an American student found stabbed to death at Baker Street station was killed with a pot shard, raising the suspicion the death may be Falcon (police code for 'Folly') related. It quickly emerges that there is not merely a supernatural component to the case but that a secret world lies beneath  the streets of the 'mundane' (non-magical) metropolis, and that the supernatural semi-human subterranean inhabitants may be no more harmless than the entirely human population who are blissfully unaware of their existence. Plot. Constables Peter Grant and Lesley May, and Detective Chief Inspector Thomas Nightingale form the magical branch of the Metropolitan Police. Grant is called in for a murder investigation at the Baker Street Underground station: the victim, American art student James Gallagher, was fatally stabbed with a pot shard. Grant visits James's art professor, and attends an exhibition of work by Irish sculptor Ryan Carroll. Peter  realises some of the pieces incorporate pottery identical to the pot shard murder weapon and a bowl found at James's flat. Following this lead, Grant and Lesley discover a warehouse where similar pottery is taken and stored. It is owned by The Beale Corporation, which was historically the maker of 'unbreakable' pottery. Its founders were instrumental in excavating the tunnels that later became the heart of the London Underground railway. Grant and a team investigate in the railway tunnels, but they are attacked by pallid large-eyed individuals. They pursue them, eventually reaching an Underground platform, where ones of  the individuals uses magic to tear the platform apart, burying Grant in the process. While Grant is recovering in hospital, Lesley tells him she has confirmed Beale, Gallagher and Carroll are all descendants of the founders of the Unbreakable Empire Pottery corporation. James' roommate Zach also visits and accidentally mentions that he knows a pallid large-eyed man. When questioned he reveals that a group known as the Quiet People has been living underground and making pottery for the Beale corporation since the mid-Victorian Era. Grant and Lesley investigate this group. As they talk to the Quiet People it  emerges James Gallagher was courting the daughter of the chieftain of the Quiet People, which made Ryan Carroll jealous. When confronted, Carroll confesses, adding that he was also jealous of Gallagher's skill in pottery.
