Reviews

Guess Who boils with claustrophobic intensity. Packed with gripping twists and turns, Guess Who is an inventive, entertaining locked room mystery that kept me utterly hooked.
Adam Hamdy
An ingenious twisty mystery in a totally unique setting.
Claire McGowan
An impressive debut and a sign of great things to come.
James Oswald
Chris McGeorge's Guess Who is a fresh take on the locked room murder mystery. The plotting is intricate, the characters well drawn, and the pace never lets up as it drives headlong to the surprising end.
David C. Taylor, Edgar-nominated, Nero Wolfe Award-winning author of Night Life
Guess Who is an incredibly satisfying, intelligent thriller running at break-neck pace right until it's closing pages. A marvellous debut.
Francesca Dorricott, author of After the Eclipse
One hotel room. Six strangers. One corpse. Good fun.
Cavan Scott
This is brilliant, so cleverly written and still surprising despite the team's love of escape rooms.
Woman's Way
A FANTASTIC whodunnit with more twists than a Great Hotel corkscrew.
