I Was Jack MortimerA man climbs into Ferdinand Sponers cab, gives the name of a hotel, and before he reaches it has been murdered: shot through the throat. And though Sponer has so far committed no crime, he is drawn into the late Jack Mortimers life, and might not be able to escape its tangles and intrigues before it is too late Twice filmed, I Was Jack Mortimer is a tale of misappropriated identity as darkly captivating and twisting as the books of Patricia Highsmith.
