The Poison Rose

Set in 1978, the plot centers on Los Angeles private investigator Carson Phillips. He is hired to conduct an investigation in his Texas hometown where mental facility patient Barbara Poole has been incommunicado for some time, which has her L.A.-based niece worried about her well-being.

Upon reaching the sanatorium, he notices that the staff all look nervous when he asks for her. Dr. Miles, the head doctor, is evasive and strings him along for several days. Carson never gets to see Mrs Poole.
