The Admiral-Superintendent, with unbecoming haste, grasped the paper and read:--
"Vice-Admiral, First Battle Squadron, Home Fleet, to Commander-in-Chief, Portsmouth. On fleet weighing anchor a painted board was found attached to the anchor of every battleship, the said board bearing the words 'With the compliments of Captain Restronguet.' Have ordered fleet to anchor again and am sending divers to investigate. Will communicate their report in due course."
All traces of irritability vanished from the faces of the two Admirals. Instinctively they realized that something of moment had taken place, and that instant action was necessary.
"A diver has been playing the fool, perhaps?" hazarded Maynebrace.
"Diver? Humph! Can you imagine a diver leaving his card, in the shape of a painted piece of wood, attached to the anchors of forty ships? No, no, Maynebrace, it's not that: at least, that's my opinion."
"Well, then, sir, what is it?" questioned the Rear-Admiral.
"A menace to our fleet, that's what it is. Although there is no real harm done the moral result is bad enough. It's my opinion that there's a foreign submarine at work. Moreover, she must have means of direct outside communication while she is submerged."
"What makes you think it is a foreign submarine?"
"Logic, my dear Maynebrace, logic. None of ours are capable of such a feat, and there's no knowing what these foreigners are up to. As inventors they are miles ahead of us. And what is more, the name--Restronguet--doesn't that sound French?"
"Perhaps," admitted the Rear-Admiral. "But all the same it is exasperating; it is humiliating. And there are some who think that the days of the submarine are over!"
