Bag-snatchers are at large in Ashfordly and the police know that Ian 'Duster' Murray and Robert 'Red' Broadbent are the perpetrators, but cannot prove it. When they attack Phil Bellamy's grandmother he takes it personally and gets determined to see them behind bars at any cost. Greengrass is also in great demand. Mr. Braithwaite has died and his daughters Joan and Norma are convinced that he hid his will in his stuffed prize ram and that Greengrass knows where it is. Jo's mother has become ill and she does her best to make Jo feel bad about it, because she will not break up her engagement to Nick and Fiona Weston cannot keep up appearances when her daughter is married to a common village bobby.
