A death threat concealed in a term paper brings Mr. and Mrs. North back to campus All semester Prof. John Leonard has directed his lectures at Peggy Mott. Not because she's beautiful--although that doesn't hurt--but because she has the sharpest mind he's encountered in all his years teaching psychology. When she turns in her final assignment, a paper on human emotions, Leonard expects a brilliant essay, but what he reads shocks him to the core: There's someone Peggy detests. And based on her paper, Professor Leonard believes she hates enough to kill. When Peggy's husband is found with a steak knife buried in his neck, the comely young student is the only suspect. But Jerry and Pamela North see it differently. Mrs. North has a mind that could drive any psychologist batty, but for the sake of a shining pupil, she'll find out the truth.Murder Is Served is the 12th book in the Mr. and Mrs. North Mysteries, but you may enjoy reading the series in any order.
