Young Colin's route home from school lies across a grubby parkland. Hiding in the bushes is a man with sweets... and a knife.

It's not like Arthur Scarsdale to be violent. He's normally a peaceful little villain, but in the Newtown nick it takes three policemen to hold him down - and all Bowker did was offer him a cup of tea.

Crime Squad from Cardiff want Inspector Moffat to lodge a prisoner overnight in the Newtown cells - and no-one must know about it. But someone has to know, even if it's only another policeman.

Lorry hi-jacks: too many, too well-planned and executed. Braithwaite goes 'under cover' as a lorry driver with a shady past. He's out in the cold - and vulnerable.

Digging a deep hole in the sand by the light of the moon isn't the sort of behaviour you'd expect from a debt collector. Not even such a strange one as Clarrie Enwright.
