The sci/fi short story I recorded, Invisible Death by Anthony Pelcher, just went on sale today at Audible.
Darius Darrow, a brilliant scientist and inventor, died suddenly and
violently in his home laboratory while his chemist wife, Susan, was
nearby. No one was seen entering or leaving the home during the crime.
The perpetrator stole Darrow's latest invention while committing the
murder. The police and the head of the company who paid royalties on
some of Darrow's patents begin the search for his killer. Death threats
in the form of letters sent to the company head begin arriving after the
murder demanding money or warning there would be more killings. What
had Darrow invented that someone would want badly enough to kill him for
A fun who-done-it from the Golden Age of science fiction. The story may be purchased here.
