Preminger made this film in the mid 60s in-between the big epic movies he made about institutions. It is on some level a return to the crime films of the 40s but the film is something else – more frightening and more mysterious. It’s shot in London and set very recognizably in the 1960s(as is apparent when The Zombies perform on TV) and into this world enters an American woman who seems to be missing her daughter. This is probably the most identifiably avant-garde of Preminger films. The narrative is linear but the mood and tone of the film, a gothic fairy tale atmosphere reminscent of The Night of the Hunter only played out in 60s London is genuinely disturbing.
