Engineer, murdered ex-husband, suitcases, Berlin tunnel
In 1955 Leonard Marnham, a naive 25-year-old British Post Office telephone engineer, is posted to Operation Gold, the joint CIA–MI6 tunnel dug under the Berlin sector boundary to tap Soviet phone lines. He falls for Maria Eckdorf, an older German divorcée, and when her violent ex-husband Otto ambushes them in her flat, the struggle ends with Otto's skull crushed. The couple spend a night dismembering the body into two suitcases, which Leonard hauls across the divided city and finally into the tunnel's secret facility, just as the operation, already betrayed by a Soviet mole, is exposed.
