When Darren Dirkowitz's evil stepbrother (code name Waldo) gets hold of Darren's tippity-top-secret spy journal, he threatens to expose it to the entire Preston Middle School student body. Unless, that is, Darren starts doing his dirty work for him. Now Darren's got to use the oh-so-cloak-and-daggery skills he's honed in his secret alternate life as Dirk Daring, Secret Agent to spy on kids at school. Naturally, he also sets up a separate, sneaky surveillance program to unearth Waldo's own secrets. As more and more ugly truths are exposed, new alliances are forged and old friendships broken. Can Darren learn to be true to himself and build real friendships for the first time in his life? Or will he retreat back into his exciting but imaginary shadow world?

Darren Dirkowitz thought his life was over when his tippity-top-secret alter ego, Dirk Daring, Secret Agent, was outed to the entire Preston Middle School student body. If only he’d been so lucky. Now the Wolf Lords—a gang of teen thugs bent on wringing every last penny out of Preston students—are breathing down his neck. There’s only one solution: Dirk Daring must embark on his most daring mission yet. A mission so audacious, so cunning, so doggone crazy, that if it succeeds, the Wolf Lords will wind up begging for mercy. But first, Darren must bring his own disobedient “associates” to heel. Let Sleeping Dogs Lie is the sequel to the runaway bestseller Dirk Daring, Secret Agent.
