An apt title to a movie that for years has been as 'elusive' as the character in the Picture!
David Tomlinson (looking very serious and attractive playing 'straight') is Mr. Barton who simply vanishes into thin air over night leaving his sister (played by Jean Simmons) alone and destitute in France at the time of the Great Exhibition'. Not only that - but all trace of him; his room, his belongings along with any records or proof of him having ever existed!
This is one of those movies that (providing you don't know the story - and thus the outcome) will keep you hooked until the very end!
Dirk Bogarde also stars, but great credit must go to the fabulous and popular Great British actress Cathleen Nesbitt who once again plays a very convincing French woman with sinister undertones.
A collection of well-known faces and stars of British cinema in this, and I can't imagine anyone disliking it.
