Plot Summary:In 2001 pathologist Bob Ruxton gave a verdict of accidental death on palaeontologist Bernard Fletcher, who died from a supposed fall at a dinner given by Mondial Oil Company in Bernard's museum. Now that verdict is declared unsound and the UCOS team reopen the case. Bernard supported ecology and disapproved of Mondial's work but, though married, he was a ladies' man having an affair with colleague Marie Braden. Marie's ex-boyfriend, Mark Slater quit the museum to set up as a trader in fossils, a lucrative business and it was alleged that Bernard sacked him for stealing exhibits. Mark would also seem to be the lover of Sarah, wife of James Winslow, Mondial's managing director. Bernard was certainly murdered but was the motive marital jealousy or greed? Jack is amazed when Bob Ruxton drops a bombshell.
