In more than twenty years, Jon Frost has worked with the mad, the bad, the brave, the stupid, the spectacular and the heroic.

In his time as a uniformed officer Jon seized presidential aircraft, a working tank, cars, lorries, boats and coffins; and uncovered wild animals, killer snakes, bush meat, animal porn, poisonous vodka, dodgy medicine, bootleg prescriptions, pirated pills, toxic alcohol, firearms, side-arms, swords, explosives, stolen gold, dirty money, blood diamonds, child pornography and every drug known to man and a few as yet unknown ones. And the dead? He searched them too.

When you've confiscated everything from a suitcase full human hair to a live monkey hidden in the lining of someone's overcoat, you know you can never return to a normal line of work.

But then Jon went into undercover customs work, and things became really interesting . . .
