'This is the kind of zany novel in which a dope-dealer’s dogs are not dobermans but miniature dachshunds, and a family of gangsters are called the Sangsters. Fans of graphic comedy — as purveyed by Chris Brookmyre and Stuart MacBride — will love it' * Times * 'a piece of very enjoyable fiction... this detective story is written with great verve and introduces us to an engaging hero' -- Allan Massie * The Scotsman * 'Relentless pace, katana-sharp humour and an endearingly irascible protagonist make Double Proof irresistibly entertaining' -- Chris Brookmyre 'A rollicking thrill-ride of a novel, whip-smart and shot through with the darkest comedy. Martin Stewart is a fresh and exciting new voice in Scottish crime fiction' -- Doug Johnstone 'a cracking good read... so witty, so caustic... the sort of book you have to read sitting bolt up' -- Breege Smyth * Oban FM * 'a heady mix of corrupt coppers, dodgy drug dealers and Japanese gangsters, all spiced with dark humour and hints of another kind of spirit' -- Sally McDonald * Sunday Post * 'a fun ride' -- Teddy Jamieson * Herald * 'A slick slice of Tartan Noir. With indelible characters and a satisfying plot . . . the book is knitted together expertly with pathos and humour to offset the gritty action within the pages' -- Stuart Johnstone, author of Out in the Cold 'There is plenty of tension, and behind the humour, a whole lot of underlying threat... The pacing of this book was spot on' * JenMedBooksBookReviews * 'Raw and amusing by turns ― occasionally even at the same time. Martin Stewart is a new and innovative voice in psychological thriller-writing to look out for' -- Carola Huttmann * Bookmunch * 'This funny, gritty novel... keeps the reader on the edge of their seat until the final page' * Jelly Books * 'a real caper... seriously laugh-out-loud' -- Michelle McManus * BBC Afternoon Show *
