The Mystery of Wrecker's Rock

The last in this series written by Arden. A little boring & standard for the 3 investigators. I was hoping for more pizazz since there's only 1 book left in the series. Not too much of a mystery that the police couldn't have solved on their own.

While attending a week-long family reunion on a California island, the Three Investigators find their photographs of the event hold an inordinate interest for someone else, and receive clues to that unknown identity from both an ancient and a modern boating accident.

Dnf. Painful and boring. I think this must be a series that you have to start reading as a kid.
