Just Making Sure

When a customer dies on the premises, Howard becomes fearful of bad publicity. He sees the dead woman's husband, Stretford, as a threat to his very existence. He desperately seeks compromising evidence, embarrassing details, in Stretford's background.
As the inquest approaches, Howard employs the salacious Mattie as an agent. But will Stretford fall for her blandishments and become vulnerable to blackmail, or will Howard become a victim of his own strategy? Dora, Howard's upright, devoted and long-suffering wife is drawn to another innocent, while Grenadier, as unscrupulous as Howard, appears to join forces with him but is too treacherous to trust.
Suspicion, blackmail, drug abuse and seduction combine in a final conspiracy of murderous intent.
