Finding himself in debt, Boon turns to his old mate, Harry Crawford for advice. The result reunion is an advertisement in the local paper: 'ex-fireman seeks interesting work - ANYTHING LEGAL CONSIDERED' - and Boon is on his way as a freelance troubleshooter.
A disheveled Irishman, who has difficulty in remembering his name, gives Boon plenty to worry about. He's apparently lost his memory, and has no inkling of where the large bundle of cash he has on his person came from.
It's hardly a glamorous job, especially when the child you're minding is Daniel, the difficult son of a rock star. But when Boon is attacked outside the boy's school and Ken realises the real target is Daniel, things soon hot up.
Hired to discover who is behind a protection racket gang who have smashed mirrors and crockery at Harry Crawford's hotel, Boon decides to take the battle to the enemy - with surprising results for all concerned.
When Harry suggests a job shifting antiques for a London dealer, Boon is not particularly keen. His market-garden business has finally taken root, and he has no wish to tempt providence again - but a job is a job.
Seeking further finance, Boon takes on a baby-sitting job with a difference - 'minding' a collection of antique clocks. What's more, Major Hopkinson, who owns them, appears to have some unpleasant acquaintances.
When Harry Crawford signs Billy 'The Kid' Buchan as the main attraction at the Fireman's Charity football match, Boon hired as Billy's 'minder', barely has time to catch his breath before the trouble starts.
With 'White Lighting' off the road' its suspension broken in an accident. Boon seeks help from a local bike dealer. A mistake. Before long he will find himself racing off on a borrowed bike - with a young Sikh girl riding pillion.
