The title suggests the first of a series in this quirky little hybrid made at Ardmore Studios set in London while shot on obviously Irish locations; but this was very much a one-off.
Anton Diffring was certainly cast against type as a debonair French detective, while several of the supporting cast (including the actress briefly seen as murdered socialite Alice Alvarez in flashback) are perceptibly post-synced, presumably to conceal their brogues. The gurgling voice of female lead Diane Hart is unmistakably Anglo-Saxon though.
