'A compelling locked room murder mystery with an unpredictable twist you won't easily forget.' Dandy Smith, author of The Wrong Daughter

‘Plenty of breadcrumb clues and red herrings to keep you guessing….a satisfying mystery all tried up in a perfect bow.’ Sarah Goodwin, author of The Private Jet

‘A plot so tightly packed with shocks that you can taste the claustrophobia.’ Diane Saxon, author or My Mother’s Lies

'A brilliantly taut setup: victim, murderer and the woman trying to get to the truth trapped together in a tube carriage. I was hooked from page one.’ Andy Maslen, international best-selling author of the Detective Kat Ballantyne series.

'A fun update on a classic crime format. This is a high-octane murder mystery with a Twenty-First Century spin. Clever use of the usual suspects who you'd meet on a late-night London tube train as suspects and a stopped train carriage as the setting. The kissing teenagers, the slurring drunks, the fatigued business people. One of them is a killer, and a passenger who's a former police inspector sets out to solve this claustrophobic crime. Great fun and a pacy read.' Chris Bridges, author of Sick to Death

‘This was a cracking read and so totally original. It had me hooked from the first page to the last. And the ending was a real shocker. Highly recommend it.’ Alex Pine, author of Killer in the Cold
