Black Mould is a graphic novel about Peter Grant written by Ben Aaronovitch and Andrew Cartmel, consisting of five comic books. It is illustrated by Lee Sullivan and coloured by Luis Guerrero, with letters by Rob Steen.

The events take place between Foxglove Summer and The Hanging Tree.[1]



The graphic novel was first published in five separate parts, and the whole story was later collected into one volume.

  • Part 1: Breaking the Mould
  • Part 2: Rumble in the Fungal
  • Part 3: Forcible Eviction
  • Part 4: Noddy's Nocturnal Adventure
  • Part 5: Guitar Solo


Peter's colleague, Muslim ninja and possible trusty sidekick, Sahra Guleed, has discovered a mould problem in the house of a friend. But what at first seems just a virulent fungus takes a far darker turn when the mould attacks Guleed, piquing Peter's interest and suggesting something far more dangerous...
