French Strikes Oil

When oil is discovered on family land, Rodney Vale sees a fortune to be made. His brother, Maurice, is worried only that the beautiful countryside will be spoiled.

The other members of the family are keen to be persuaded by Rodney, but without Maurice's permission they have no power to act.

When Maurice is murdered, Inspector French is puzzled by mismatching gloves found on the body - one his own, the other a woman's.
