Here's a short story:

CHAPTER XII 

Throughout the night reigned an almost sepulchral silence, and when the morning broke, the _City of Boston_, at a scarcely reduced speed, was ploughing her way through great banks of white fog. The decks, the promenade rails, every exposed part of the steamer, were glistening with wet. Up on the bridge, three officers besides the captain stood with eyes fixed in grim concentration upon the dense curtains of mist which seemed to shut them off altogether from the outer world. Jocelyn Thew and Crawshay met in the companionway, a few minutes after breakfast. 

"I can see no object in the disuse of the hooter," Crawshay declared querulously. "Nothing at sea could be worse than a collision. We are simply taking our lives in our hands, tearing along like this at sixteen knots an hour." 

"Isn't there supposed to be a German raider out?" the other enquired. 

"I think it is exceedingly doubtful whether there is really one in the Atlantic at all. The English gunboats patrol these seas. Besides, we are armed ourselves, and she wouldn't be likely to tackle us." 

Jocelyn Thew had leaned a little forward. He was listening intently. At the same time, one of the figures upon the bridge, his hand to his ear, turned in the same direction. 

"There's some one who doesn't mind letting their whereabouts be known," he whispered, after a moment's pause. "Can't you hear a hooter?" 

Crawshay listened but shook his head. 

"Can't hear a thing," he declared laconically. "I've a cold in my head coming on, and it always affects my hearing."  (End of story)
