After Della Street buys a package of memorabilia dealing with a woman, Helen Cadmus, who died a year ago, she and Perry are approached by Nathon Fallon who it seems is prepared to pay any price to get his hands on the material on behalf of his employer, Benjamin Addicks. Perry is intrigued and asks Paul Drake to look into Addicks' background . They soon track down a former housekeeper, Josephine Kempton, who is in the process of suing Addicks for slander as he has been spreading lies about her being a thief. Addicks is a strange man, a scientist who keeps a menagerie of animals including a gorilla. When Josephine calls Perry from Addicks' home asking for help, he arrives to find the gorilla in Addick's bedroom and Josephine on the floor avoiding the glare of the gorilla, who has seemingly gotten out of its enclosure. Addicks is dead but when the police find that he has been stabbed, it's clear that someone other than the gorilla was involved. Written by garykmcd

Monkey Business
1 January 2013 | by (Buffalo, New York) – See all my reviews

In an effort to be original within the Perry Mason parameters the writers came up with a rather scenario for a plot. I fear it was all a bit much for my poor old head to take in.

Barbara Hale who buys some memorabilia at an auction belonging to super model Charlene Holt brings Victor Buono in his most unctuous manner to Raymond Burr's office. Holt was reported drowned after falling off the yacht of an eccentric millionaire and Buono works for him. After being rebuffed by Burr, Buono leaves in a huff and soon afterward another of the man's retainers Gavin McLeod contacts him and Perry and Della are at the man's house.

Before long the millionaire is killed, first thought to be by a gorilla he kept on the estate and later by former cleaning lady Lurene Tuttle. She becomes Mason's client.

I won't say more, but the solution to all of this is a truly bizarre one and for once there is more than one murderer involved. It doesn't quite come together in this episode.
