THE MISSING LINK is a pretty interesting episode of the Colonel March TV show, at least for this viewer; I've always been interested in prehistoric skeletons, the Piltdown Man hoax, etc. and this skirts familiar territory. The plot is straightforward - a museum housing a rare and contested specimen known as the 'Missing Link' is broken into and the skull stolen - but the plot thickens when it becomes apparent that the skull wasn't there in the first place.
Various human intrigue surfaces, and it's left to March and Ames to unpick the plot strands and work out what really happened. Although THE MISSING LINK lacks the kind of recognisable faces in the cast that made other episodes interesting, the story is enough to see this one through and the life-or-death climax is a fun, pulp-style one.
