Police Precinct Part 7

Just when we thought the Cold War was over, leave it to these guys to heat it up again.

The body of a woman was found in a manhole. Is it an affair? The victim is a clerk at a mannequin manufacturing company. At the age of 26, she was a widow with a child, and she went missing after he went to collect her salary from the bank. A colleague at work said the victim was wearing an opal ring, but the bank clerk says she wore a jade ring when he came to withdraw money.
