This tight little ticking-clock tale, adapted from the teleplay The Gold Inside, is a prime dramatic showcase for Hammer icon Peter Cushing as a spit-and-polish bank manager whose branch gets a holiday-season visit from security tester André Morell (reunited with Cushing after The Hound of the Baskervilles)—only, this is not a drill. The production design is by Hammer staple Bernard Robinson, working on a budget considerably lower than the sum at stake in the plot.
