Palace Guard on CBS

A former thief is hired to head security for the international hotel chain he used to target. The ex-criminal, who also happens to be the illegitimate son of the founder and president of the company, travels around the world investigating break-ins, thefts and murders, employing rather unconventional means. He doesn't actually do too much trouble-shooting: the show was canceled after three episodes. Stephen J. Cannell was the executive producer.
