Elizabeth Cubbon, known to everyone as "Aunt Bessie," is delighted to see two of her friends being united in marriage. But before the wedding, there's a cold case that has the whole island talking.

Aunt Bessie likes helping Hugh Watterson and John Rockwell with their investigation.

But when the three girls who went missing decades ago turn out to have been murdered, Bessie isn't as happy to be involved. When one of the main suspects turns up dead, things look increasingly complicated.

Aunt Bessie doesn't really like surprises.

But she's determined to give the happy couple the best possible surprise she can arrange. She just has to find time to plan that while hunting down a killer.
