Plot

The remains of Sloan's friend are found in a shark, which is made all the more suspicious when it's discovered the victim had three wives.

Just when Jesse takes a now unamused girlfriend sailing, the harbor master brings in a shark that swallowed an arm of rich stock broker Preston Michaels, presumably having fallen overboard, plausibly drunk; but the autopsy soon finds he was fatally poisoned with digitalis, which also killed the shark with a heart attack from the poisoned arm. Curious Mark condoles respectable widow Bea and learns from lawyer Raymond Bergman that he is named executor of the estate. Preston on a posthumous video admits he was a bigamist, having two younger wives in other states, fitness freak Heather (Florida), and Terri (Colorado) who was told he wanted a divorce. All of the wives deny knowing about the others but lack alibis, while Preston's personal assistant, Susan Stimpson, says she managed his triple life. Raymond Bergman calls Mark to tell him whom he suspects is the murderer but just then is killed by his pool. The firm's VP Evan Houston, now acting CEO, also was in the house and asks Mark for $50,000 of Preston's capital for firm expenses. Steve finds Stimpson fully packed, with a one-way ticket for Bermuda and a fortune in cash, from blackmailing Preston. Mark keeps snooping...—KGF Vissers
