Agatha Raisin and the wizard of Evesham - M. C Beaton

The local ladies all deem Mr John a wizard, so when Agatha finds a few grey hairs on her head - and the rinse she tries at home turns her hair purple - she makes a beeline for the handsome Evesham hairdresser. And as well as sorting out her hair it soon becomes clear the charming man also has designs on her heart - but their future together is cut short when Mr John is fatally poisoned in his salon.

Once again Agatha finds herself embroiled in a murder case. Was it one of Mr John's many customers, all of whom divulged to him their darkest secrets?
