"Two Crafty Criminals by Phillip Pullman is a collection of two stories, featuring a group of young detectives called the New Cut Gang. The stories really are separate from each other and even feature different gang members. The first story, Thunderbolt's Waxwork, follows Sam Thunderbolt as he tries to figure out who is making the fake currency that has been showing up all over town. His father is suspected, and even Thunderbolt is not entirely sure of his Dad's innocence. Thankfully he has his friends in the New Cut Gang to help him get to the bottom of this mystery. The second story, The Gas-Fitters' Ball, features the mischievous twins Angela and Zerlina. Their older friends are in love, but having a hard time becoming engaged. To make matters worse, someone has stolen the silver from the Gas Fitters dance hall!"
