Mystery House - that strange publishing firm\nowned by Dan and Barbara Glenn - where each new novel is acted out by the\nMystery House staff, before it is accepted for publication. Mystery House was a\nprogram in the 1950\xe2s, but not your run of the mill type program. Actually it\nwas more of a proving ground for novels. Dan and Barbara Glenn owned a\npublishing company named \xe2Mystery House\xe2\xa0\nlocated at 70 Park Avenue, New York City. Dan and Barbara decided to\ntest some of their novels on a real listening audience. Each episode was taken\nfrom a novel they were planning on publishing. The entire staff at Mystery\nHouse was involved,\xa0 everyone doing their\npart, whether it was rewriting to adapt it to radio, playing the parts or doing\nsound effects, everyone joined in. Sadly, not a lot is known about this series.\nOnly 15 are known to exist.
