This is a real "sleeper" (no pun intended), a tight, compact suspense film that really keeps moving throughout its economical running time. The cast is uniformly superb, the direction is assured and fluid, and the film is a reminder of just how many quality low-budget films were made even into the 1960s, before the collapse of the double-bill and the end of black and white as a commercial medium. Well worth looking for; I don't know if the film is available on tape. It should be.
