Big name actors including Sondra Locke, David Soul, and Tim O'Connor make for an entertaining episode of Cannon.
The viewers know from the start who the real killer is, but it takes Cannon quite a bit of sleuthing to get past the mentally unstable "Trish Caton" (actress Sondra Locke) and the conniving "Sean Caton" (actor David Soul).
Cannon's former fellow police officer, "Lieutenant Fred Norris" (actor Malachi Throne), provides a great foil. There are also some interesting marine biology lessons thrown into the mix. The only questionable scene is "Dr. Paul Bridges" (actor Keith Charles) confronting a drug dealer face to face, unarmed and with no witnesses on hand.
Overall, a very good story. I rate "Death of a Stone Seahorse" 9 stars.
