Agatha Raisin and the Wizard of Evesham (Agatha Raisin, Bk 8)

Mrs. Agatha Raisin fancied herself to be a detective to rival the fictional ones like Poirot and Lord Peter Wimsey. She was a stocky middle-aged woman with good legs, a round face and small bearlike eyes which looked suspiciously out at the world

But only that week she had discovered nasty gray hairs appearing all over. She had bought one of those colour rinses, but it had turned the gray purple. "Go to Mr. John," advised Mrs. Bloxby, the vicar's wife. "His place is in the High Street in Evesham. He's supposed to be a wizard at tinting hair."

After a home dye job ruins her hair, Agatha Raisin, the prickly yet lovable amateur sleuth, turns to the wonderful new hairdresser in the neighboring town for help. And as Agatha soon learns, Mr. John is as skilled at repairing her coiffure as he is at romancing her heart.

But the charming Mr. John isn't all he appears to be. According to gossip around the salon and the village, some of his former clients seem to be afraid of him. Could Mr. John really be a ruthless blackmailer? When a murderer strikes at the busy salon, Agatha must discover the truth and the killer's identity before it's too late.
