All but one of the unclued lights can be preceded by DOCTOR (or in one case DOC). The title also explains why DOC’s name (as the compiler) was omitted from the heading of the puzzle. Solvers were required to highlight CAPE at 38 Down which yields ‘Cape Doctor’ where Doctor follows rather than precedes the unclued light.
First prize Storm Hutchinson, Dulas, Anglesey
Runners-up Philip Whiteland, Doveridge, Derbyshire;
J. Frankland, Storth, Milnthorpe, Cumbria
