Pins and Needles

A vintage Humber car is found rammed into an old Oak tree on a country lane; a bright Summer's day, no-one else on the road. The seat-belt might have saved the driver if only he'd bothered to put it on. But was it the crash that killed him? Or was it suicide? Or might he have been dead already, the result of a heart condition the retired Councillor had lived with for over nine years, a Councillor with a passion for vintage cars, professional ballroom dancing and other men's wives.
