A brand new Golden Age cosy crime mystery from the multi-million-copy bestseller Faith Martin. 'Hugely entertaining with an ingenious solution! I loved it!' Clare Chase 'A wonderful book with which to cosy up’ The Belfast Telegraph 'A masterfully constructed pageturner of a murder mystery. Clever, compelling, and intriguing. An excellent read' T.A. Williams ***** Yorkshire, 1926. Gentleman ghost-hunter Arbuthnot 'Arbie' Swift and his old friend Val arrive at Cleeves Lea Manor, looking forward to the promise of a lavish weekend party. The lady of the house, an avid reader of Arbie’s books, is eager to show him off to her distinguished guests. Amidst the festivities, Arbie is also tasked with investigating rumours of a ‘ghost train spitting fire’ for the third instalment of the increasingly popular (to Arbie’s great surprise) Gentleman’s Guide to Ghost-hunting. But when the guests start dying, Arbie instead finds himself thrust into the middle of a murder investigation. With time running out, will he and Val be able to uncover the truth?
