'Mesmerising, macabre and murderously funny. The Botanist is M.W. Craven at his sinister best. I couldn't love this series more' Chris Whitaker'Another classy thriller from the king of Cumbrian crime' Paul FinchThis is going to be the longest week of Washington Poe's life...Detective Sergeant Washington Poe can count on one hand the number of friends he has. And he'd still have his thumb left. There's the guilelessly innocent civilian analyst, Tilly Bradshaw of course. Insanely brilliant, she's a bit of a social hand grenade. He's known his beleaguered boss, Detective Inspector Stephanie Flynn for years as he has his nearest neighbour, full-time shepherd/part-time dog sitter, Victoria.And then there's Estelle Doyle. Dark and dangerous and sexy as hell. It's true the caustic pathologist has never walked down the sunny side of the street, but has she gone too far this time? Shot twice in the head, her father's murder appears to be an open and shut case. Estelle has firearms discharge residue on her hands, and, in a house surrounded by fresh snow, hers are the only footprints. Since her arrest she's only said three words: 'Tell Washington Poe.'Meanwhile, a poisoner called the Botanist is sending the nation's most reviled people poems and pressed flowers. Twisted and ingenious, he seems to be able to walk through walls and, despite the advance notice given to his victims, and regardless of the security measures taken, he is able to kill with impunity.Poe hates locked room mysteries and now he has two to solve. To unravel them he's going to have to draw on every resource he has: Tilly Bradshaw, an organised crime boss, even an alcoholic ex-journalist. Because if he doesn't, the bodies are going to keep piling up . . .
