From the authors of the "excellent" Mr. and Mrs. North Mysteries: Captain Heimrich investigates family secrets behind closed doors (TheNew Yorker).   Capt. M. L. Heimrich of the New York State Police may not have the flash of hard-boiled city detectives, but there's no lead the intrepid investigator won't follow until his every hunch is satisfied . . .   After four years serving as a lieutenant in the US Naval Reserve, all World War II widow Jane Phillips wants is to reunite with her great-aunt Susan Meredith at her home in Westchester, New York. But Jane's journey soon proves to be fraught with danger.   First, a series of unfortunate events almost causes Jane to miss her train. Then, another passenger attempts to trick her into a premature disembarkation. Jane would like to think the mishaps are simple coincidence, but what she doesn't know is someone doesn't want her to make it home at all . . .   When Susan's grandson insists the family matriarch is being poisoned to death, police detective Captain Heimrich is duty bound to investigate. And soon he'll uncover a dastardly plot involving greedy relatives, a woman in peril, and the kind of wealth some people would kill for.   I Want to Go Home is the 1st book in the Captain Heimrich Mysteries, but you may enjoy reading the series in any order.
