Turtle opens the first of the safe deposit boxes. Its owner is a crooked gentleman named Bullitt who runs a protection racket with publicans as his victims, and there is enough evidence in the box to put him away for several years. Turtle, who is very fond of publicans, plans to turn the tables on him.

Turtle and Eddie's next hoard contains, in Supt. Rafferty's words, "skeletons from cupboards, dynamite, and the dirt from under a lot of carpets." And they would rather not be in posession of a war-hero general's last will and testament - particularly when his throat-cutting ex-colour sergeant shows up.

Turtle and Eddie find themselves in posession of papers belonging to Al Shapiro, one of the most ruthless contract assassins in the business. With enough incriminating evidence to earn him life sentences in several countries, the pair are handling something more dangerous than dynamite!

Box number four is the property of one Ras Patel, a vicious property racketeer who is exploiting poverty-stricken Asian immigrants while running a highly corrupt empire in his native country. Turtle quickly sees an opportunity to perform a philanthropic deed - at no cost to himself.

Turtle and Eddie set out to bring a crooked casino owner to justice when the latest box is found to contain evidence of blackmail and computerised fraud. In doing so, they have the unconventional help of an ambitious senior Army officer - although their old enemy Rafferty is not far behind.

A new box is opened, revealing what seems to be hire-purchase agreements; £450 million worth, in fact. "Sounds like a lot of furniture", says Eddie. The men who drew up the agreements think so too. So does the CIA - and the deadly undercover man who stamped "Official Secrets Act" on them.
