There is some uncertainty why Burr was “missing” from this episode and the following three. The Perry Mason TV Show Book (1987) says he was “in the hospital for minor dental surgery.“ The Ona L. Hill biography Raymond Burr (1994) says “he went into the hospital on December 10, 1962 for major surgery.” She goes on to say, “He had been diagnosed with potentially cancerous intestinal polyps, which turned out to be benign. A part of his intestines was cut away and a Dacron tube inserted.” I recall hearing from somewhere that, in later years, Burr denied cancer rumors about himself. Perhaps this explains the differing stories? The Hill story is supported by newspaper articles of the time. However, one article (Newport, R.I., Daily News, Feb. 11, 1963) says Burr “has been quoted as saying that they [the polyps] were cancerous.” It goes on to say “he has declined any further statements beyond declaring that he was fortunate in all regards.” Does anyone have any additional information?

+ Yes, but not reliable. Burr appeared on a later talk show and, while demurring at specifics, stated he had a physical difficulty which, while not serious, prohibited him from being able to stand or move comfortably. Not much help, is it? Submitted by CGraul, 9/5/2011.

These four "guest lawyer" episodes were the only episodes from the first six seasons not available in the original 195-episode syndication package of the 1970s. Other episodes not available were all but 4 episodes of the 7th season ("Deadly Verdict" was not shown), the entire 8th season and 16 episodes of the final season ("Dead Ringer" and "Twice-Told Twist" weren't shown but "Final Fade-Out" was). It wouldn't be until the mid-1980s until the other 76 episodes would be shown when TBS bought the rights. Submitted by Wiseguy70005, 6/15/12.
