Series 12

Shabnam Chowdry is a young Asian girl. Roy Grant is a young white boy. Put them together and knives are drawn - and Lynch is in the middle.

Newtown Marriage Guidance Centre has been burned down, so Haggar and Bowker start investigating its clients. They are looking for a man or woman with a grudge - a man or woman who will strike again.

A policeman can only take so much. Lynch deals with the problem one way, Quilley another. Trouble is, in Quilley's case there's a woman involved.

Night duty in Newtown is a rough turn; not the place for a young policewoman. But WPC Jane Beck won't listen to the warnings of Inspector Lynch.

Roger Stevens is the quiet sort of copper, always there. Perhaps that's why Lynch tends to take him for granted. But sometimes it's the quiet kind one needs to worry about most of all.

Freddie Cowling has come out of prison a changed man. He's lost a lot of weight, he's got a degree and he's promised his wife he'll go straight from now on. But Lynch doesn't believe he's changed. Not when there's the proceeds of his last job to be collected - £40,000 hidden away and waiting...

Sunday - kids who have nothing to do. First Lynch, then Haggar gets involved - they do have something to do.

Frank Rafael Saietta has come home to Newtown. Lynch remembers him as a nice little lad, but that was years ago. Now there are different words to describe him - terrorist and murderer.

Lynch holds the balance between C.I.D. and the Customs & Excise as they investigate a bent businessman and a suspicious German ship. The only link between them is a showgirl.

Maureen Price was always complaining to the police - so much so that they'd stopped listening. The pity is that if they hadn't she might be alive today.

Two men face retirement, one a policeman, the other a villain. There are younger men impatient to fill their shoes. The copper has no choice about it, but the villain has other ideas.

A new security shutter is being installed at the entrance to Newtown station, just in time, it seems, as an angry mob gathers outside. A stream of visitors keeps the desk duty officer busy.
