Austin Trevor dons a French accent in this cryptic murder mystery. Two bodies have been found with the torn pages from an impoverished silent film star's diary in their dead hands. "Pierre Santos" pitches in to help to establish a motive for these seemingly random killings and to detect the culprit who must be staying at the grand home of "Lady Groombridge". This is quite a pacy affair. Nothing novel but given it had a very low budget and some very uninspired direction, it is a simple quota feature from Twickenham Studios that easily passes an hour.
