Finlay Donovan is no stranger to skeletons in the closet . . .
But this murder is too close to home.
Finlay Donovan and her nanny/partner-in-crime, Vero, have not always gotten along with their elderly neighbour, Mrs. Haggerty – the community busybody and president of the neighbourhood watch.
But when a dead body is discovered in her backyard and her house becomes an active crime scene, there’s nowhere for her to stay . . . except at Finlay’s, right across the street.
Finlay and Vero have no interest in getting mixed up in another murder case – or in sharing their beds with Mrs Haggerty. But when police suspicions land on Finlay’s ex-husband, Steven, they’re left with no choice.

3. Murder in Covent Garden by Anita Davison

Nobody should be in the market⦠for murder!
Even though its famous opera house has shuttered its doors for the war, Covent Garden remains one of the most exciting, bustling areas of London. Itās where Hannah Merrill and Aunt Violet have their bookshop and, in spite of the recent spate of burglaries in the area, itās generally thought to be a good neighbourhood.
So Hannah is surprised when she sees a fellow shopkeeper ā a jeweller named Jacob Cornelis ā having a heated argument with a stranger. Especially when the next day Cornelis is found dead in his shop, apparently the victim of another burglary.
But what shocks Hannah more is when she meets the policeman supposedly there to investigate the crime. Because he is none other than the man who Hannah saw arguing with Cornelis the day before.
Hannah knows itās up to her and Violet to investigate. But they donāt know theyāre about to uncover a secret underworld of theft, murder and blackmail. And they must act fast, before the Covent Garden Killer strikes againā¦

4. Husband Missing by Lisa Regan

Fear prickles her skin. āNoah?ā Photos and trinkets from their simple but perfect life together litter the carpet. The coffee table is cracked, blood along its edges. She should be taking in details, but her heart is racing too fast. A strangled cry works its way from Josieās chest. Where is her husband?
Detective Josie Quinnās world shatters when she returns home to find her house ransacked, and her husband, Noah, missing. When she kissed him goodbye hours earlier, called to the discovery of a womanās body at a protest, they were putting the finishing touches to a nursery for their first adopted child. But now the house is empty, Noahās bloodied handprints trailing the walls.
Every fiber of Josieās being screams to investigate. But her team warn her to keep her distance as they follow a connection to a recent robbery in Denton. But Josie canāt quiet the voice telling her the handprints Noah left are leading her somewhere, and the trail ends at an upturned box of her long-dead abusive motherās possessions: faded photos, jewellery, a lock of hair, and a few old newspaper clippings.
Beside herself with worry for Noah, and unexpectedly confronted by the trauma of her past, Josie throws herself into work. The womanās body found during a demonstration outside a childrenās hospital belongs to Gina Phelan, daughter of the powerful and influential Phelan family. Trawling the CCTV is a welcome distraction, but everything changes the moment fingerprints from the knife that wounded Gina match to prints found in Josieās own home.
Her head spinning as the two cases collide, Josieās only option is to delve into the life of the monster who terrorized her as a child. The key to everything is hidden in the box of her motherās mementoes. But is Josie strong enough and fast enough to find it in time? And at what devastating cost to those she loves most?

5. Marriage and Murder by Stephanie Laurens

When a middle-aged spinster is found strangled in her country cottage and scurrilous gossip implicates Henry, Lord Glossup, he appeals to Barnaby and Penelope Adair along with Inspector Stokes to unravel the mystery of who killed Viola Huntingdon.
Henry, Lord Glossup, arrives on Barnaby and Penelope Adairsā doorstep and begs their aidāand that of Stokesāin identifying the murderer of Viola Huntingdon, a middle-aged spinster who lived a largely blameless life in a country cottage in a tiny village close to Henryās home. As Stokes has already been tapped to take the case, the investigators travel to Salisbury and thence to Ashmore village and throw themselves into the case.
While initially Henry was touted as a suspect, he is quickly eliminated, and with the help of the victimās sister, Madeline, the investigators set out to discover all they can about the victim and who might have wished her ill. In such a small village, with a commensurately small population, the list of possible suspects is short, but the existence of Violaās āsecret admirer, Hā has everyone stumped. First, how could Viola, living in such a small community, have had a secret visitor, a man no one saw except at a distance? And who on earth is he, this H?
As the investigators piece together the clues of missing jewellery and sightings of H and follow the leads generated by opportunistic thieves, dodgy jewellers, and local moneylenders, a picture emerges that points to only one conclusion. But in small villages, things are rarely as they seem. Have the investigators got the right man in their sights, or have they been led astray?
