"Murder off the Books" by Evelyn David was co-written by one of my on-line buds.
It's a mystery with a little twist; it's got a lot of humor in it. With three goofy teenagers, that goes without saying. There's also a scooter-bound elderly neighbor who wants in on the action. And a local exterminater trying to get his work-truck back. Seems the funeral director takes vehicles(or beef) as colleteral and "The Bug Man" wants his back without paying the bill.
Mac Sullivan has been hired by the insurance company to investigate the embezzlement of half a million dollars from the local college. Then the bodies start to pile up. Dan Thayer is the prime suspect. His sister Rachel knows better. So she's caught between the cops and her brother. And the three teenagers trying to clear "Uncle Dan."
I didn't guess who the murderer was, but I have to admit I never get it right. I pinned it on someone 1/3 of the way into the book and at the 2/3 mark, I knew I was wrong. I did enjoy the book. It didn't take me long to read and I want another. Since I'm able to contact the author I'll be nagging her for a sequel.
Oh yeah. I like the Irish Wolfhound, Whiskey, too.
