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? Praise for the Agatha Raisin series: 'M.
Beaton's imperfect heroine is an absolute gem.
' Publishers Weekly 'The detective novels of M.
Beaton, a master of outrageous black comedy, have reached cult status.
' The Times 'Being a cranky, middle-aged female myself, I found Agatha charming!' Amazon customer review 'Agatha Raisin is sharp, witty, hugely intelligent, unfailingly entertaining, delightfully intolerant and oh so magnificently non PC.
M C Beaton has created a new national treasure.
the stories zing along and are irresistible, unputdownable, a joy.
If you buy one book a year, let it be this.
Agatha Raisin is The Strongest Link.
