Havaí 5.0: Most Likely to Murder

SINOPSE

Honolulu policeman Lew Morgan appears to be cracking after his wife is killed. Morgan also is an old friend of Five-O's Dan Williams, who takes a personal interest in the case. It turns out that Morgan's wife, Marjorie, had affairs with other men. The lead suspect is Gary Oliver, a criminal who was Mrs. Morgan's latest lover. Morgan kills Oliver, an apparent case of a grief-stricken husband taking vengeance. But Five-O's probe shows the case is more complicated.
