Peter Grant is the protagonist of the series. He is a London police constable and apprentice wizard. He is 25 years old at the start of series.[1]


Peter has a very positive albeit slightly wry outlook on life. He is curious and innovative, but very easily distracted, sometimes by magical vestigia, more frequently by beautiful women. Though his decisions may be occasionally rash, they are always well-intended and he has an earnest desire to protect innocents. He has been described as a "cheeky bugger".

Early life and familyEdit

Peter Grant was born the University College Hospital, London, to Richard 'Lord' Grant and his wife Rose, a Fula, from Sierra Leone, ca 1987. He grew up in the Peckwater Estate, off Leighton Road in Kentish Town. He ran away from home twice when young, although he returned of his own will on both occasions. Before joining the police, he was planning to study architecture, but gave up because his draftmanship was awful.[1] At one point, he worked in a coffee kiosk which was "a bastard to work in".[2]

He has several cousins: Abigail Kamara[3] and Obe (an electrician?).[4] Peter also has an uncle named Tito[5] and an aunt named Jo.[3]

He is of mixed race and describes himself, using the police jargon, as "between IC3 and IC6".

In Whispers Underground Peter receives a winding black and silver Omega watch from Thomas Nightingale as a Christmas gift.[11]

Although he only earned a 'C' grade on his Chemistry A-levels, Peter has an excellent understanding of the scientific method.[5] Because of this he is often frustrated by unquantified or poorly defined magical entities and phenomenon. Peter has personally invented or re-discovered multiple modern measures for detective work that also deals with magic. Some of these experiments include:

  • Invention of the Yap scale
  • Experiments determining whether magic damages transistors and vacuum tubes.[9]
  • The approximate distance another practicioner can sense a spell being formed.[9]
  • What materials retain vestigium the longest.[4]
  • How to sacrifice electronics (e.g. cell phones) in place of animals for spells.[5]
  • How to tap into the potential energy of an electronic device for magical purposes.[9]
  • Timing the length of a spell's effect.[3]

Magical Education Edit

Inspector Nightingale has occasionally expressed irritation over Peter Grant's ability to be side-tracked by scientific details and has, at times, admonished him for spending time on experiments rather than working on advancing his magical learning.[4] At other moments, Nightingale has expressed admiration for Peter's quick thinking and creativity in his use of magical forms; in particular, after Peter faces off with the Faceless Man during Moon Over Soho.[9]

Peter is the first officially sanctioned practicioner since 1945, and therefore did not receive the standard pre-WWII training regime that started during primary school. Because of this it is often hard to measure his magical aptitude as a practicioner. In Broken Homes Nightingale admits that he would not have been able to detect specific signare when he was at Peter's level of apprenticeship, but follows this by saying, 'I was only 12 at the time and easily distracted'.[4]

As of Lies Sleeping Peter's abilities include first through third order spells and some fourth order spells such as shields and magnification.

Other Skills Edit

Peter seems to have picked up a broad range of non-magical skills from friends and family. In particular he has a professional knowledge about industrial and residential cleaning, and is familiar with the dust and build-up accompanying this job. This skill originated with his mother, Rose Grant, who works as a cleaner.[5] During Peter's teenage years he often assisted her with cleaning jobs where he developed this skill.[3][12]

He has a solid understanding of the scientific method, electronics, computer systems, and a deeper knowledge of music (especially jazz), architecture, and police procedures.

Languages Edit

During the course of the series his Latin language skills readily improve with his spell work, although he admits his Greek is not particularly good.[12] He speaks English and at least understands Krio (a Creole language in Sierra Leone).[4] He learnt German in school, but only speaks a few words.[5]



Beverley Brook Edit

Peter is currently in a long term relationship with Beverley Brook. Although they were initially attracted to each other, their relationship did not begin until she began assisting Peter in the investigation described in Foxglove Summer. As of Lies Sleeping, they are expecting their first child.[12]

Past Relationships Edit




Peter Grant has been portrayed by Kobna Holdbrook-Smith in the audiobook version of the books, and by Doc Brown (Ben Bailey Smith) at a reading of the short story King of the Rats in 2015.
