- The Times
Brilliant! THE POISON TREE grabs you with the first sentence and doesn't let go — even after the last page; this is the sort of thriller that stays with you for a long, long time. Compelling and lyrically stylish, THE POISON TREE is a true winner! 
- Jeffery Deaver, New York Times bestselling author of The Edge and The Burning Wire
Intoxicating...Kelly gives readers a compelling creeper that intelligently invokes the conventions of the Gothic [and] offers the twisted pleasures of vengeance within its eerie narrative. 
- Washington Post
An unusually good debut psychological thriller from an author who instinctively knows how to tell a suspense story and whose plotting, characterisation, fluent writing and dark humour should ensure her a successful career. 
- Daily Mail
[An] intriguing and well-written mystery.
- Washington Times
Tense and menacing right from page one, filled with foreboding and a terrible sense of the inevitable. Kelly builds a feeling of claustrophobia and of seemingly ordinary people driven to do extraordinary things. It's a gripping psychological thrill...and I expect the author to go far.
- Bookseller
In her compelling debut, Erin Kelly evokes the brooding atmosphere of Rebecca in a contemporary and completely convincing novel of tangled family desires. 
- Sara Paretsky
The spirit of Daphne Du Maurier hangs heavily over Kelly's debut novel, from the gloomy old Highgate house where the heroine is lured to the unnerving, claustrophobic denouement. A taut chamber-piece of psychological suspense. 
- Financial Times
A wonderfully tense and foreboding thriller that is at the same time a clever, considered study of desire and a good old-fashioned page-turner. 
- Psychologies
A brilliant new voice in crime fiction... Kelly expertly builds up the suspense... For a debut, The Poison Tree is extremely accomplished - Kelly creates an atmosphere as claustrophobic as a summer commute, which permeates the narrative and keeps the reader hooked.
- Stylist
Ingeniously plotted and masterfully told, THE POISON TREE is an outstanding debut from Erin Kelly. A spellbinding tale of murder, guilt, and obsession, it will hold readers in suspense from the first sentence until the final shocking twist.

Kelly deftly weaves past and present in her highly satisfying debut…the tension never wanes, and the ensuring horror comes as a major shock. The surprises don't end until the last page of this twisted tale with its wonderfully evocative London atmosphere.
