Murder on Monte Vista - Pederson David S. Pederson - Bog

It's 1946, and on a hot spring night in Phoenix, Arizona, things are only beginning to heat up at the Monte Vista Road home of flamboyant decorator Walter Waverly Wingate. Private detective Mason T. Adler isn't thrilled to be turning fifty, and the party Walter throws him makes him even more uncomfortable. Walter has arranged a special birthday present for Mason: a private hour with the handsome, young Henry Bowtrickle in Walter's upstairs bedroom. But the night turns deadly when his birthday gift turns up murdered. The room was locked, no way in or out, and only Henry and Mason were inside. Mason Adler is on the case, but he is also a suspect, along with the other assorted party guests who were all downstairs at the time of the stabbing. Or were they?
