Lux Radio Theater - A Blueprint for Murder

Whitney "Cam" Cameron arrives at a hospital to be with his
widowed sister-in-law Lynne, whose stepdaughter Polly has died
under mysterious circumstances. A doctor cannot determine the
cause of the child's death.


Cam has great affection for his young nephew Doug. He begins to
fear for the boy's life when Maggie Sargent (Catherine McLeod),
the wife of his lawyer, Fred, mentions that the dead girl's
symptoms sound suspiciously as if she had been poisoned.


Fred reveals that the will of Cam's brother, who also died from
unspecified causes, put all his money into a trust for the boy.
Lynne would inherit it all if anything happened to Doug.


Police, prodded by Cam, exhume the girl's body. Poison is found
and Lynne is brought to court, but a judge dismisses the charges
for a lack of evidence against her.


A desperate Cam cannot think of any way to keep Doug safe,
particularly once Lynne decides to take the boy away to Europe
for at least a year. Cam surprises them by turning up on the
ocean voyage. He begins romancing Lynne, all the while plotting
to poison her.


He slips a tablet from her belongings into a cocktail. Lynne goes
to great lengths to castigate Cam for his suspicions and
demonstrate that the tablet contained nothing but aspirin. Cam
leaves her stateroom, but a few minutes later Lynne's life is
saved by the ship's doctor .....
