Pregnant and grumpy, Polly yearns to escape the increasingly annoying advice of family and friends. When an opportunity comes up to travel to England to attend a puppetry conference, she jumps at it, in spite of her "delicate condition". The trouble starts when someone tries to steal her luggage at the airport, and by the time she arrives in Canterbury, she knows someone’s stalking her. When another woman is found dead, a mangled puppet nearby, the question arises - is Polly next? Set against the backdrop of the ancient town where Thomas Becket was murdered, this fourth Polly Deacon mystery places puppet-maker Polly in the middle of a pea-souper fog, eluding a persistent thug, refusing to cooperate with the police and desperately trying to stay out of trouble. This is hard to do - when you’re sleuthing for two.
