Review by clanciai

It starts very innocently with no danger at all as there is only one old man dead by suicide, at it seems. Guy Rolfe is there to help the young heiress Barbara (Rona Anderson) who gradually appears as a target for someone who wants to kill her for some reason, but at the shooting party organised for her execution, someone mysteriously shoots the executioner, whom no one in the vicinity has ever seen before. The plot and the mystery thickens.

There is a backward boy at the stables who stammers and seems to generally falter in everything he does, but he knows something and sees what no one else sees and makes observations. This is perhaps the most important and interesting character in the film, and he will continue acquiring more importance to the bitter end, as more and more people get murdered one way or the other, and there are some very nice foggy London scenes at night when Rona and Guy break in to investigate some dark secrets. That's where the actual film and excitement starts, which then mercilessly will increase to the desperate end.

The backward groom with something of a zombie about him is actually Stanley Baker at an early stage. He remains the most fascinating character, nothing wrong about the others, they are all excellent on a small scale, but the plot gets more and more knotty as it develops. There is more than one murderer here, and they will all surprise you.
