This was the first episode in the ATV series which ran for three years during the 70s at prime time on Saturday nights in the UK. The series consisted of hour-long thrillers starring a strange cross-section of GB and US actors. Scripted by Brian Clemens who created the series initially, this episode is a spin on a standard thriller plot.
Plain-Jane American girl holidaying in England (Barbara Feldon, unknown in the UK so obviously a ploy to sell the series to the US) is swept off her feet and all the way to the altar by charming but secretive Robert Powell - who looks all of 15. Sadly for la Feldon she is but a pawn in the game of Powell and real wife Linda Thorson (minxing it up) who plan to kill her so they can claim Thorson's life insurance. However when Powell learns that Feldon is actually worth more than the insurance money the plan starts to go awry.
The plot races along blithely ignoring the obvious improbabilities and the three leads, along with T.P. McKenna as a possible spanner in Powell's works and Mary Wimbush as a sullen cleaner, play it straight.
Like all the THRILLER series, location shots are kept to a minimum with most of the action being shot on videotape in studio sets. It's great this series in now available on DVD to refresh memories of 1970s TV viewing! An added bonus on the DVD are the laughably tacky ITC credits tacked on for it's showing on US TV.
