Death-Wish Green — Frances Crane

Did she jump -- or was she jumped? A sleuthing couple looks into the disappearance of a young woman on the Golden Gate Bridge . . .
 
An abandoned car on the Golden Gate Bridge usually carries the sad suggestion of suicide. But after Pat and Jean Abbott spot the car in the fog and learn that it belongs to a friend's niece, Katie Spinner, they begin to suspect that she is not in a watery grave but in the clutches of a kidnapper.
 
When one of Katie's friends -- who was supposed to go with her to the North Beach arts festival -- turns up dead, the mystery of the missing young woman becomes only more challenging in this compelling 1950s mystery in the long-running PI series.
