The Policeman's Daughter

Fisher's younger daughter has left home after a row and thrown in her lot with a group of squatters. He asks Crabbe to find the girl and try and persuade her to return home. Henderson has bought a new field to add to his market garden, but is horrified to find that it has been invaded by travellers. He appeals to Henry for help, whereupon Henry finds that the two cases have a common thread.
