Welcome to Christmas, a town so cozy and charming it could be the backdrop of a Hallmark movie. So when a tourist is found stabbed to death by an icicle ornament in the middle of the town nativity scene, the local police are out of their depth. Special Agents Holly Frost and Mark Shepherd are on thin ice after screwing up on the job. This assignment is their one shot at redemption, if they can put aside their bitter rivalry. And of course, it's not only their careers on the line, it's their hearts, too. Regrets of their holiday party hookup last year haunt them like ghosts of Christmas past, so they both want to wrap up this rom-com gone wrong as quickly as possible. But with just 12 days until the town's annual Jingle Bell Jubilee festival, the countdown to catch a killer --- without killing each other --- is on.

Finlay Donovan’s nanny and partner-in-crime, Vero, has been extradited from Virginia to Maryland, where she’s facing criminal charges for a theft she swears she didn’t commit. A prisoner to an ankle bracelet as she awaits her trial, Vero is forced to live with her overbearing mother and nosy aunt. Threatening messages keep arriving on her mother’s door, demanding that Vero “turn over the money…or else.” But proving her innocence might be an impossible feat. Vero was the treasurer of her sorority when the money went missing --- one of the only people who had access to the cash. And her alibi is a date who ghosted her. With her court date quickly approaching, and her mysterious stalker on her tail, she needs to clear her name fast. Finlay sets off on a mission to suss out the real thief and bring Vero home.

Finlay Donovan and her nanny/partner-in-crime, Vero, have not always gotten along with Finlay’s elderly neighbor, Mrs. Haggerty, the community busybody and president of the neighborhood watch. But when a dead body is discovered in her backyard, Mrs. Haggerty needs their help. At first a suspect, Mrs. Haggerty is cleared by the police, but her house remains an active crime scene. She has nowhere to go…except Finlay’s house, right across the street. Finlay and Vero have no interest in getting involved in another murder case --- or sacrificing either of their bedrooms. However, when the focus of the investigation widens to include Finlay’s ex-husband, Steven, Finlay and Vero are left with little choice but to get closer to Mrs. Haggerty and uncover her secrets…before the police start digging up theirs. But who will solve the mystery first?

Finlay Donovan and her nanny/partner-in-crime, Vero, plan a trip to Atlantic City. But odds are it won’t be all fun and games --- seeing as it’s actually a cover story to negotiate a deal with a dangerous loan shark; save Vero’s childhood crush, Javi, from a kidnapper, Marco; and hunt down a stolen car. When they sneak into the loan shark’s suite to search for clues, they find more than they bargained for: Marco is already dead. They don’t know who murdered him, only that they themselves have a very convincing motive. Will Finlay fold under the pressure and come clean about the things she’s done, or be forced to double down?

Finlay Donovan has been in messes before --- after all, she's an author and single mom who’s a pro at getting out bloodstains for rather unexpected reasons --- but none quite like this. She and her nanny/partner-in-crime, Vero, accidentally destroyed a luxury car that they “borrowed” in the process of saving Finlay’s ex-husband. The Russian mob handled her debt, but that means Finlay now owes them. Still running the show from behind bars, mob boss Feliks has a task for Finlay: find a contract killer before the cops do. Problem is, the killer might be an officer. Luckily, hot cop Nick has started up a citizen’s police academy, so Finlay has the perfect cover-up to sleuth out the real criminal as she does some “research” for her new novel. Nick is more than happy to get close to Finlay, but he’s also getting dangerously close to the truth.

Finlay Donovan is once again struggling to finish her next novel and keep her head above water as a single mother of two. On the bright side, she has her live-in nanny and confidant Vero to rely on, and the only dead body she's dealt with lately is that of her daughter's pet goldfish. On the not-so-bright side, someone out there wants her ex-husband, Steven, out of the picture. Permanently. Whatever else Steven may be, he's a good father, but saving him will send her down a rabbit hole of hit-women disguised as soccer moms, and a little bit more involvement with the Russian mob than she'd like. Meanwhile, Vero is keeping secrets, and Detective Nick Anthony seems determined to get back into her life.

Finlay Donovan is a stressed-out single mom of two and struggling novelist. The new book she promised her literary agent isn’t written, her ex-husband fired the nanny without telling her, and this morning she had to send her four-year-old to school with hair duct-taped to her head after an incident with scissors. When Finlay is overheard discussing the plot of her new suspense novel with her agent over lunch, she is mistaken for a contract killer and inadvertently accepts an offer to dispose of a problem husband in order to make ends meet. Soon, Finlay discovers that crime in real life is a lot more difficult than its fictional counterpart, as she becomes tangled in a real-life murder investigation.
