Burke's Law - Season 2 Episode 12 : Who Killed 711? 1966

This victim was scheduled to go before a grand jury but was slain in a hotel elevator before he could testify. The solution to the crime must be in his hotel room, 711, but in order to solve the case, Burke goes undercover as a maitre d'. Tim and Les, meanwhile, are recruited as waiters, much to the dismay of the hotel manager. All the clues seem to point directly to the victim's befuddled bookkeeper, but this may be a frame-up. The others who have been subpoenaed, and who have good reason to want the victim dead, include a businesswoman with a fiery temper, the victim's attorney, his sexy assistant, and a shady rival businessman. Burke just narrowly misses being shot in a dark alley as he finds the clue that solves it all.
