Edward Phillips Oppenheim 
The Zeppelin’s Passenger 

Excerpt:
‘Never heard a sound, ‘ the younger of the afternoon callers admitted, getting rid of his empty cup and leaning forward in his low chair. ‘No more tea, thank you, Miss Fairclough. Done splendidly, thanks. No, I went to bed last night soon after eleven—the Colonel had been route marching us all off our legs—and I never awoke until reveille this morning. Sleep of the just, and all that sort of thing, but a jolly sell, all the same! You hear anything of it, sir?’ he asked, turning to his companion, who was seated a few feet away.
