'If It's A Man, Hang Up' opens Thriller's fifth series with a slow-burning tale of voyeurism and obsession.
The ravishing Carol Lynley stars as Suzy Martin, a stylish and beautiful model who leaves in a salubrious apartment with her dog and no man. A series of upsetting calls to her telephone commence - taking a variety of forms; silence, heavy breathing, toneless invocations of her name; whispered sweet nothings... To complicate matters and make life difficult for Suzy and the helpful police it seems that there a few possible suspects namely - Terry (her photographer), Greg (her part-time lover) and Murchison (the somewhat sinister caretaker)
Two further male characters which make their way into Suzy's web. The first is Terry's Sicilian friend Bruno Varella (aka Bruno 'Something') played to perfection by Tom Conti while the second is the over helpful policeman Hal (the younger of a pair of friendly bobbies) who reckons that the suspect can be caught if he and Suzy join forces.
As if this backdrop of harassment wasn't enough things take a turn for the worse when Suzy's brother Peter is killed by a hit and run driver following a night spent in his sister's flat. The finger points to the mysterious caller and the suspense is upped when Hal persuades Suzy to spend the weekend at his remote country cottage.
The climax is very dramatic with an inventive twist. Caril Lynley would go on to keep the suspense anthology torch burning with a excellent performance in Hammer House Of Mystery And Suspense's 'In Possession' nine years later.
But back to 1975 - 'If It's A Man, Hang Up' is a quality episode of Thriller that will keep you engrossed.
