This is the sixth in this series featuring reticent Stella Darnell, running a cleaning company, Clean Slate, who has established a part time career as a private detective since she solved the mystery of her father's, a policeman, death. Underground train driver Jack Harmon, offbeat and intuitive, the complete opposite of Stella, is her partner in this side of her business. The pair find themselves moving to Winchcombe in Gloucestershire to look into the death of 2 young women who disappeared in two different time periods. In 1977, Cassie Baker heads home after a village disco only to never be seen again, assumed to have escaped to London. In 1999, DCI Paul Mercer is led to Cassie's remains by Charlie Brice, a suspect behind the disappearance of Bryony Motson, a banker's daughter. Mercer has always been convinced that Charlie murdered both women, despite the conviction of another man for Cassie's murder. For the last 18 years, despite being forced out of the police force for not following procedures, Mercer has relentlessly pursued Brice, but without success, he is now dying.
Lisa Mercer is Paul Mercer's daughter, and whilst she is less than happy with her father, she persuades Stella to take the case. Jack is over the moon, he has the opportunity to spend time with Stella who he loves unconditionally, and he waxes lyrical about the romance behind having a client who is a detective's daughter, just like Stella. Jack's past relationship with illustrator Bella has repercussions in the present as Bella informs he is about to become a father to twins, but she is unwilling to let him get involved in their lives. Lonely journalist, Lucie May, is on the hunt for her exclusive and sees the advantages of working with Stella and Jack to achieve her aims. Stella and Jack are staying at The Crow's Nest, a ruin of a house, with no facilities such as electricity or wifi. Sinister events suggest that there are forces who want them to leave, such as the odd constant movements of a weird scarecrow, dead crows left in the house and drones observing their activities. Lucie joins them camping out in the house with her talkative bird, Endora. The case turns out to be a complex sprawling affair, with a brazen and confident Brice residing openly under the shadow of suspicions cast on his character. Is he guilty or is someone else behind the heinous acts? And what exactly is Jackie and Barry's involvement, if any?
This is a great addition to the series, streaked throughout with plenty of humour and comic touches, particularly with Endora repeating anything she hears. Stella's approach to her murder cases follows the lore of her cleaning manuel, to tackle them stain by stain. It is hardly a surprise that her expertise in her cleaning profession infuses the descriptions of places and the odours of cleaning products. Stella and Jack are an odd couple who happen to complement each other's characters and abilities, both covertly drawn to each other, but hesitant about breaking cover over their feelings for each other. What I like is how the author has built a host of characters that feel so familiar but who still have the capacity to surprise such as Jackie and Barry. An absorbing and entertaining crime series. Many thanks to Head of Zeus for an ARC.
