It is October 1940 and undertaker Francis Hancock is called out to Epping Forest to attend to the corpse of a young gypsy girl who has died suddenly. At the wake, a gypsy named Lily claims to see a vision of the 'Blessed Virgin'. Meanwhile the Military Police are looking for a German - Martin Stojka - who they believe is a Nazi spy. Then Lily is found stabbed through the chest. Could it be a crime of passion or cold-blooded murder? Is Martin Stojka who he says he is? There is someone lurking in the shadows who will stop at nothing to find what Martin has in his possession.
