Perfect for you if...

  • You love crime thrillers with genuine humour woven through dark subject matter, where the detective feels as real as your mate down the pub.
  • You're drawn to locked-room mysteries and impossible crimes that actually have clever solutions rather than hand-wavy explanations.
  • You appreciate quirky ensemble casts where side characters like a shepherd and a caustic pathologist are just as memorable as the lead detective.

Maybe not for you if...

  • You prefer psychological thrillers with unreliable narrators and twist endings over methodical police procedurals with strong logic.
  • You want your crime fiction gritty and bleak without levity or moments of character-driven levity breaking the tension.
  • You're reading the Washington Poe series for the first time and want to start from book one rather than jumping to this later instalment.

About this book

Winner of the Theakston Old Peculier Crime Novel of the Year 2023. Detective Sergeant Washington Poe has few friends: civilian analyst Tilly Bradshaw, Detective Inspector Stephanie Flynn, his neighbour Victoria, and pathologist Estelle Doyle. When Estelle's father is found shot twice in the head, evidence points to her—firearms discharge residue on her hands and only her footprints in the snow surrounding the house. After her arrest, she speaks only three words: "Tell Washington Poe." Simultaneously, a killer dubbed the Botanist by the press is targeting high-profile celebrities, sending them poems and pressed flowers before striking. Despite police precautions and advance warning to victims, the killer appears to operate with impunity, seemingly able to bypass all security measures. For a detective who dislikes locked room mysteries, the week ahead will test Poe as he navigates both cases.
