"The Lady gives Jack a gift. It's a lab kit! Jack goes into the shed to experiment and doesn't come out until he's made another Jack and another Jack and another. But one Jack was already too many. Can Jack stop his naughty robot clones before they destroy the town?"--publisher

An impish rabbit takes a purse--and a lipstick--from a grey-haired lady and uses them and Rex, a dog, to get into mischief.

Jack and the Lady take the train West to visit a dude ranch. One night, there's a bank robbery next door, and Jack is pegged as the bandit. But thanks to Jack's new rope tricks, the real robber is caught, and Jack leaves the Wild West a free rabbit with a big secret.

When Jack finds himself on the naughty list, he worries that Santa will bring him coal. But Jack wants presents--lots of them. Will Jack be able to prove to Santa that he's not so bad after all?

In 1989 someone is threatening to steal the crown jewels, so the Queen of England summons Mac B. to England to protect them--and when they are stolen from a locked dungeon cell, where Mac and Holcroft, one of the warders, are supposed to be guarding them, it is up to Mac to figure out how they were stolen, and whether the thief is the descendant of an Irish soldier-of-fortune who tried to steal them in 1671, or someone else entirely.

There is a legend that if the ravens at the Tower of London ever leave then Britain will fall, so when somebody steals the birds, the Queen calls for Mac B. to find the thief and retrieve them--a mission that takes him to Iceland, where he encounters secret submarines, hungry polar bears, and his arch-nemesis from the KGB.
