Carol Lynley does some fabulous work here as American woman newly arrived in England whose little daughter is apparently kidnapped from school on her first day. The catch is, nobody knows the child and Lynley is having trouble proving she even exists! Terrific mystery from director Otto Preminger, an uneven filmmaker who does strong work just up to the finale (which is somewhat anti-climactic). Laurence Olivier is the police inspector on the case and he's very smooth, cunning and yet sympathetic to Lynley. There are some mod overtures which seem misplaced, and Noël Coward has a gratuitous bit as Carol's drunken landlord (and BBC celebrity!), yet the film does have many sharp bits of minute detail, intriguing and funny supporting characters, terrific cinematography and locations. Does it all add up? No, but it's inscrutable fun nevertheless. *** from ****
