The Keepsake by Tess Gerritsen

This was a perfect diversion read. Not too heavy or complex - just your traditional murder mystery. A well preserved mummy shows up in the basement of a museum, but turns out to not be thousands of years old as first thought. The police are brought in and the plot continues to thicken, twist and turn enough to keep you on your toes not knowing exactly how it's going to play out. I stayed up late several nights reading this novel, and fortunately it didn't give me the creeps even though there are a number of no-so-nice images described in the book.
