Lost Homicidal Maniac (Answers to Shirley)

The fourth book in the wildly popular series of horror/comedy novels featuring Andrew Mayhem!
In this dark and hilarious new adventure, Andrew has started up a private investigation business with his best friend Roger (slogan: "We Solve Weird Problems"). Since his options in life will become somewhat more limited after his wife Helen gives birth to triplets, it's his last-ditch effort to get out of being stuck with a corporate day job.
One of their first clients is an attractive woman named Shirley. Keeping with the kind of luck Andrew has had his entire life, her problem is: "I think I may be a serial killer."
Yeah, he takes the job. Even after she insists on being handcuffed to him while they investigate the house where she might have stored the bodies of her victims.
But Andrew discovers that this day has much more danger in store than being handcuffed to a woman who may or may not be a homicidal maniac. Because Mr. Burke, the sadistic villain of his last adventure, has been watching Andrew and plotting a truly ghastly revenge...and the attack begins now!
Packed with the trademark demented humor, wild action, and grisly horror you've come to expect when Andrew Mayhem is involved.
