Mystery! (also written MYSTERY!) is a long-running television series that premiered on PBS in 1979 and is produced by WGBH. The show has allowed a large number of detective series and television movies, most of them British productions from the BBC or various ITV companies, to air on American television.
The first host of the show was film critic Gene Shalit. He was soon replaced by Vincent Price, who hosted the series from 1981 to 1989. Since then, the series has been hosted by Diana Rigg.
