Every time my best friend Hazel and I try to transition out of cleaning other people's homes and into anything else, we end up cleaning up a crime scene in our sleepy hometown of Cooper's Cove, Maine.

Our latest job sounds perfect—preparing the inside of an old lighthouse for the town's Festival of Lights. Before we can scrub the place spic and span, we're face-to-face with a mummified murder victim in the lighthouse's basement!

When a local paranormal investigation group jumps at the chance to connect with the dearly departed, a member of their team goes missing, leaving no shortages of suspects. Adding insult to injury, all clues suggest that her disappearance is tied to the mummy. Go figure.

As the clock strikes down to the festival's opening day, Hazel and I dust off our sleuthing skills and race against her law enforcement brother in a mad dash to see who can solve the mysteries first.

Can we find the person—or persons—behind these crimes before it's lights out for us?
