Mystery House - that strange publishing firm
owned by Dan and Barbara Glenn - where each new novel is acted out by the
Mystery House staff, before it is accepted for publication. Mystery House was a
program in the 1950âs, but not your run of the mill type program. Actually it
was more of a proving ground for novels. Dan and Barbara Glenn owned a
publishing company named âMystery Houseâ 
located at 70 Park Avenue, New York City. Dan and Barbara decided to
test some of their novels on a real listening audience. Each episode was taken
from a novel they were planning on publishing. The entire staff at Mystery
House was involved,  everyone doing their
part, whether it was rewriting to adapt it to radio, playing the parts or doing
sound effects, everyone joined in. Sadly, not a lot is known about this series.
Only 15 are known to exist.
