The House on Telegraph Hill begins in a very dark place indeed, Belsen concentration camp where two Polish widows have been imprisoned. Karin Dernakova and Victoria Kowelska befriend each other amidst the horrific conditions of the camp. But although Karin has much to live for, Victoria is the stronger and more determined character. Karin dies just before the camp is liberated, and Victoria Ė with nothing left in her native land Ė makes a momentous decision that ultimately will lead her into unimagined danger.
Director Robert Wise is unhurried in setting the scene of the movie. His use of Victoria as the narrator of the early scenes gives the audience a clear understanding of her situation and helps to establish her as a sympathetic character.
When Belsen is liberated by American forces, Victoria is interviewed by the kindly Major Marc Bennett (played by William Lundigan), and takes the irrevocable step of declaring that she is Karin Dernakova. She has Karinís identity papers, and has learned all about her friendís life and family. Karinís young son Christopher was sent to America before the war to live with Karinís wealthy Great Aunt Sophie, from whom Karin is to inherit a great deal of money.
Italian actress Valentina Cortese plays Karin (formerly Victoria) with a believable combination of integrity and desperation. We know that she is good person from her efforts to protect her friend. And from her narration we know that she took her dead friendís identity not for the sake of money but to find security and normality again after her terrible wartime experience.
Eventually Karin reaches the United States and meets Alan Spender (Richard Basehart) who was appointed as Christopherís guardian following Great Aunt Sophieís death. After a whirlwind courtship, they marry and go to live in the imposing mansion on San Franciscoís Telegraph Hill, where Karin happily becomes a mother to Christopher and revels in her newfound normal life.
Before long, though, Karin starts to feel that all is not as it seems. The housekeeper cum governess, Margaret, makes it plain that she resents Karinís presence. And even Alan seems to be keeping secrets from her. As her suspicions deepen, Karin tries to find answers but this only puts her in greater danger.
I found The House on Telegraph Hill to be a gripping psychological thriller. Its element of film-noir comes partly from the dark settings and cinematography, and also from the situation of the lead character. Karinís life is threatened because of who she is Ė even though she is not that person; a dark and seemingly inescapable dilemma.
The acting in the movie is very high quality. Richard Basehart (who was married in real life to Valentina Cortese at this time) brings Alanís complex character to life, and gives us some very effective scenes of smiling menace. Fay Baker is excellent as Margaret, hovering between politeness and fury in such a way that we can only guess at her characterís true motivations.
I highly recommend The House on Telegraph Hill as an involving mystery thriller.
