Moving from Room 17 on a Peel Research Fellowship Oldenshaw and Dimmock find themselves in new surroundings in a university. Can they put their experience to use when fire takes hold of a wood yard just after it has changed hands?
A press article stirs the Fellows' interest and they start finding some information about the movement of contraband goods by an otherwise legitimate haulier.
A person on the Fellows' list of the 30 biggest criminals funds legitimate businesses via the profits from extortion and the illegal car trade. But where is the proof beyond circumstantial evidence?
To see where it leads, The Fellows arrange for two men who have been released from prison to be followed. They were part of a gang who committed a cash robbery, the proceeds of which have never been found.
Following up on their earlier plan to trap Spindoe, The Fellows are delighted when their car with a tracker gets stolen and when one of the gang offers evidence against others in it. However, the path of justice may not run smoothly.
As part of their research, The Fellows arrange for some criminals to get information about some poorly guarded isotopes then work out how they will attempt to steal them so that the police may catch them in the act. But will the plan work?
The relationship between Oldenshaw and Dimmock continues to fracture. Meanwhile, in India a man is murdered in a London gangland killing. Why in India and how does this link to the Fellows?
The Fellows and Mrs Hollinsczech get into a drunken discussion; there is a fire at a travel agent and a customer wants their money back and some American thugs want to take over a club. How do these all link together?
