Mabel Wickles has just entered the computer age.  And not a minute too soon.  With strange lights emanating from the empty house next door, her dear friend Charlie Thompson accused of murdering a woman, and a new sheriff in town who seems totally unqualified, will this senior sleuth use her new little laptop to dig up some clues?  After all, she is Parson’s Cove’s most highly decorated amateur detective.  (She’s Parson’s Cove’s only amateur detective.)  But with her best friend Flori Flanders and her computer mentor Nathan Horne to support her, maybe Mabel can solve these seemingly unrelated mysteries and not have to disturb the town’s favorite Sheriff––Reg Smee––who is just starting to enjoy his retirement in Hawaii.  That is, if she can figure out how to crack all the new-fangled computer jargon and SAVE AS MURDER.
