Tell No One (15)

Tell No One stars the excellent François Cluzet as a pediatrician whose wife was murdered eight years ago - or was she? One morning there's a cryptic email in his inbox purporting to be from her, so he rushes to find out whether her death was faked, with his sister-in-law, Kristin Scott Thomas, on hand to help. The mystery's solution is mind-numbingly convoluted, but there's more than enough tension beforehand to suggest that this Hitchcockian French thrillerwould still be remembered fondly today if it had starred Harrison Ford or Michael Douglas in the 1980s.
