The book is apparently quite genuinely by George Manville Fenn, judging by its style and content. Yet it does not appear on any list of his books, and copies of it seem to be very rare. For that reason we have not been able to put a verified publication date on the book. It does not even appear in the British Library's catalogue, indicating that it was possibly not registered for copyright. It is fairly short, taking but three hours to read aloud. It was published in the same cover as "The New Forest Spy," which is approximately of the same length, so that they can both be regarded as longish short stories.
