The case of the counterfeit eye

the long version

Perry Mason's office. L.A. Usual kinda day. In walks Peter Brunwold who hires Mason because someone has replaced his precious, skillfully made glass eye with a cheap imitation, so, Brunwold suspects, the stolen eye can be planted at the scene of a murder. Later, Bertha McLane asks Mason to return some money to high roller Hartley Basset which her brother embezzled from him. When Mason goes to Basset's house, the guy's wife Sylvia stows away in Mason's car so she can tell him her husband is holding her prisoner. That's just the first day. Wait till day two when Basset is found murdered, clutching -- you guessed it -- a glass eye
