The Butcher's Studio production of "Night of the Prowler" is predictable but plausible fun. Director Francis Searle and scenarist Paul Erickson make the most of this micro-budget thriller about a madman who systemically wants to eliminate the owners of a racing car company. Searle's direction is snappy and this hour-long, black & white thriller is serviceable enough to maintain attention. John Horsley steals the show as Scotland Yard Detective Inspector Cameron. The villain is ambitious, but the suspense is lacking because you suspect what is going to happen before it does. Nevertheless, it doesn't waste time going about its business.
