'In a lonely house upon an unfrequented part of the Norfolk coast a retired Cambridge professor is living by himself. Gradually he becomes aware that his house, which is built upon the site of an age-old ruined church, is being watched. In his perplexity he appeals to Gilbert Larose. The mystery and dreadful happenings of all that follows after form another exciting chapter in the life-story of the one-time great international detective.

'Here, Arthur Gask has again written one of those outstanding mystery stories which have secured for him his enviable reputation.'
