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.

Quilley was at school with Chris Murray and knows he wouldn't hurt a soul. So when Chris half murders a man and pleads guilty Quilley wants to know why.

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.

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.

It's his first day as a sergeant and Alec Quilley's hung over. It's his first job as a sergeant, and it requires a bit of gentle persuasion. But how can you be gently persuasive to a double-barrelled sawn-off shotgun?
