S4E22 The Case of the Cowardly Lion

Hilde Fursten and Tony Osgood are employees at the San Diego Zoo. When a baby monkey goes missing, Dr. Walther Braun, a visiting dentist, points the finger at Hilde. Meanwhile, Boris Zelbowski, who also works at the zoo, is in a relationship with Frieda Crawson, Dr. Braun's nurse. Later that evening, Dr. Braun comes to the zoo for an oral surgery on a lion, but he is discovered dead inside the lion's enclosure. The investigation turns against Tony when a witness claims to have seen someone in his blue sportcoat near the scene at the time of the murder.
