"This is Sophie Hannah at her wry, ingenious best. A super-relatable what-would-you-do, with a sting in the tail on the very last line. Don't miss it." -- Gillian McAllister, New York Times bestselling author

"Funny, clever and audacious. I bloody loved it!" -- Jennie Godfrey, #1 international bestselling author of The List of Suspicious Things

"An utter joy. This is a murder-mystery about the lengths you would go to to protect the person you love. It is a ferocious battle between good and evil, a tense, page-turner of a book with so many clever avenues, plus *the* most enormous plot twist (Agatha would be in awe). As if that wasn't enough, it's also incredibly funny, extremely entertaining, and a brilliant study of human behaviour. I would totally, one hundred percent do what the Lamberts have done. Wouldn't you?" -- Joanna Cannon, bestselling author of The Trouble with Goats and Sheep

"[A] daring metafictional mystery...a witty and entertaining ride." -- Publishers Weekly

"Hannah has surely written a true original... readers who love this book will love it...for dog-loving mystery fans." -- Kirkus Reviews

"Hugely entertaining and infectiously funny, this joyous adventure is one of Sophie Hannah's very best books. A delight from start to finish." -- Alex Michaelides, #1 New York Times bestselling author of The Silent Patient

"I loved this. Such a clever, twisty book with as many layers as a matryoshka doll plus I loved the meta-fictive aspects. Works on so many levels. Bravo!" -- Harriet Tyce, bestselling author

"If you think there's nothing new in crime, this is the book to read. Truly original." -- Stuart Turton, bestselling author of The 7 1/2 Deaths of Evelyn Hardcastle
