Yellowthread Street is a 1990 ITV police drama about detectives of the Royal Hong Kong Police based on the novels by William Leonard Marshall. In the Yellowthread Street series, the detectives of the Yellowthread Street police station in fictitious Hong Bay, Hong Kong -- DCI Harry Feiffer, a European born and raised in Hong Kong; Senior Inspector Christopher O'Yee, half-Chinese, half-Caucasian American, and all neurotic; and the ever-bickering team of Inspectors Auden and Spencer -- attempt to find the rational basis for inexplicable and seemingly bizarre crimes. For example, in 1988's Out of Nowhere, DCI Feiffer must figure out why in the pre-dawn hours, four people in a plate-glass-filled van with Chinese opera blaring out the tape deck were driving on the wrong side of a deserted motorway, miles from the nearest on-ramp, before dying in a violent collision with an oncoming lorry. And why, moments before the collision, did one of the passengers shoot the van driver? Thirteen fifty minute episodes were made. Cast members included: Ray Lonnen, Bruce Payne, Robert Taylor, Tzi Ma, Mark McGann and Catherine Neilson. Tetchie Agbayani appeared in one episode.
