Frank is visited by a solicitor from Yorkshire, Drummond, who is trying to trace Jenny Graham, a young woman from Beverly. Jenny disappeared some weeks ago and her mother is concerned to find her. It's an edgy meeting and Frank holds out few hopes of success but takes the job.
Upon leaving her train Jenny was befriended by a man called Peter Mason. He spotted she was new to the city, and quickly established that she had no contacts and nowhere to stay. She is quite defensive with him but is still willing to accept his support. It soon turns out that Mason is a pimp and gets Jenny working for him as a call-girl.
Frank makes some enquiries and eventually strikes lucky when driver Phil White says he has spotted Jenny. However tracking down Miss Graham is the smallest part of the problem. The hard-faced Jenny has taken to her new work like a duck to water and is unreceptive to advice. Meanwhile Mason has tried the same "introduction" on another new arrival from Sheffield, Sue Forbes. However lurking behind Mason is the outwardly respectable and urbane Dannon who is rather a bigger fish in these murky waters. He has his eyes on Jenny and intends to get what he wants...
