Detective Superintendent Harriet Martens of Greater Birchester Police is lounging near a pool on a hot August afternoon, sipping a Campari soda, when she suddenly experiences strange and violent symptoms. Harriet is fortunate; the quick action of her husband, John, and the skills of an expert doctor bring her through what could easily have been a fatal attack. It seems that an unknown assailant slipped a poison called aconitine into Harriet's drink. In H. R. F. Keating's new mystery, "A Detective at Death's Door," other poisoning victims follow, and they are not as lucky as Harriet.
Harriet's recuperation is slow. She is ordered to stay at home for three months, lest she suffer a relapse. However, she cannot lie still while a killer is still at large. She is determined to assist DS Pat Murphy, the Senior Investigating Officer on the case, even if it means dragging herself out of her sickbed. And that is exactly what Harriet does, much to the consternation of her worried husband.
"A Detective at Death's Door" is a breezy and very funny mystery featuring a detective who is irrepressible, curious, and impulsive. Harriet Martens is a determined woman with a vivid imagination. She doesn't suffer fools gladly, but she is willing to make a fool out of herself if it means finding the murderer who tried to kill her. Keating's dialogue is droll, and this book features a whole array of delightfully eccentric British characters. I enjoyed Miss Earwaker, a former teacher and plant expert nearing eighty who takes Harriet on an expedition to find the source of monkshood, the plant from which aconitine is derived. Another memorable character is Harriet's next-door neighbor, Mrs. Pickstock, an extremely solicitous individual who tries to keep Harriet in bed and offers Harriet tasteless organic concoctions to speed her recovery.
Keating keeps the proceedings moving along briskly, and although the story's resolution is not entirely logical, that is almost beside the point. Fans of British police procedurals will be diverted by this entertaining and lighthearted mystery.
