Agatha Raisin and the Love from Hell by M.C. Beaton
Recently married to James Lacey, the witty and fractious Agatha Raisin quickly finds that marriage, and love, are not all they are cracked up to be. Rather than basking in marital bliss, the newlyweds are living in separate cottages and accusing each other of infidelity. After a particularly raucous fight in the local pub, James suddenly vanishes - a bloodstain the only clue to his fate - and Agatha is the prime suspect."
Agatha Raisin and a Spoonful of Poison by M.C. Beaton
Cranky but lovable sleuth Agatha Raisin's detective agency has become so successful that she wants nothing more than to take quality time for rest and relaxation. But as soon as she begins closing the agency on weekends, she remembers that when she has plenty of quality time, she doesn't know what to do with it. So it doesn't take much for the vicar of a nearby village to persuade her to help publicize the church fete---especially when the fair's organizer, George Selby, turns out to be a gorgeous widower.
Agatha Raisin and Kissing Christmas Goodbye by M.C. Beaton
Agatha Raisin is bored. Her detective agency in the Cotswolds is thriving, but she'll scream if she has to deal with another missing cat or dog. Only two things seem to offer potential excitement: the upcoming Christmas festivities and her ex, James Lacey. This year she is sure that if she invites James to a really splendid, old-fashioned Christmas dinner, their love will rekindle like a warm Yule log.
Agatha Raisin is lonely. Busy as she is with her detective agency and the meetings of the Carsely Ladies' Society, she still misses her ex-husband, James Lacey, so she welcomes his return to the cottage next door with her usual triumph of optimism over experience---especially when he invites her on holiday at a surprise location that was once very dear to him. With visions of a romantic hideaway in Italy or the Pacific dancing in her head, Agatha goes off happily with James to...Snoth-on-Sea, in Sussex.
