Former stand-up comic Juno Mulligan has been suffering a serious sense-of-humour failure. Not only has she lost the love of her life, but she’s having to relocate to the (admittedly idyllic) village of Inkbury to watch out for her elderly mother, who she’s genuinely worried might be marrying a wife-killer. She hopes that her old friend, disgraced-journalist-turned-novelist Phoebe Fredericks can help her crack the case of whether her mother’s perma-tanned, iceberg-smiled, three-times-a-widower fiancé is hiding a murderous past.

Widow Mimi lives on idyllic Mackinac Island, where cars are not allowed and a Gibson martini with three onions at the witching hour is compulsory. Her estranged granddaughter, Addie, is getting over the heartbreak of not only being dumped by her fiancé, Brian, but also being cut out of the deal for the brilliantly successful video game Murderscape they invented together (with Addie doing most of the heavy lifting).

London, 1941: Miss Jane Treen is at her desk, strong black coffee in hand and fluffy ginger cat by her side, when her top-secret government work is interrupted by an urgent call to Devon. A woman has been found dead in a lake in a place where she shouldn’t have been. Jane needs to gather the clues and find the killer before someone else from the agency gets hurt… Shy and handsome code-breaker Arthur Cilento is bewildered by the arrival of the efficient Miss Treen and her cat Marmaduke.

Dorothy Graham is dead, which is inconvenient, not least for her. Luckily, she has planned for this eventuality. Now, if any of the truly dreadful people she is related to want to get their hands on her money, they’re going to have to do so via a fiendish difficult and frankly bizarre competition of Dorothy’s devising. After all, just because you’re dead, it doesn’t mean you can’t enjoy a last laugh at the expense of people who made your life miserable.

When private investigator Matthew Hill picks up the call from his wife, Sally, his world comes crashing down. Their eight-year-old daughter, Amelie, is missing. One second, she was there, the next, she was gone. It’s the very nightmare they’ve been dreading. Long ago, Matthew left the force after a woman blamed him for her son’s death, promising that he too would one day feel her pain. It’s a threat that’s hung over his family ever since, and now it’s Amelie’s picture on the news.
