“Montague!” the airman repeated. “Do you know her Christian name?”

“Jean Montague,” was the German’s response as he busied himself carefully screwing down one of the terminals of an instrument.

Noel Barclay made a quick note of the name in a tiny memorandum-book which he always carried in his flying-jacket.

He offered the German one of his cigarettes—an excellent brand smoked in most of the ward-rooms of His Majesty’s Navy—and then endeavoured to obtain some further information concerning his dead shipmate’s visitor.

But Herr Strantz, whose sole attention seemed centred upon the shore-end of the new cable which was so soon to form yet another direct link between Berlin and London, was in ignorance of anything connected with the mysterious young person.

The statement that Harborne—the motor-cyclist who had spoken the German language so well when he had accompanied the pretty young girl the day before to watch the testing—was dead, seemed to cause the cable-engineer considerable reflection. He said nothing, but a close observer would have noticed that the report of the murder had had a distinct effect upon him. He was in possession of some fact, and this, as a stranger on that coast, and a foreigner to boot, it was not, after all, very difficult to hide.

Noel, however, did not notice it. His mind was chiefly occupied in considering the best and most diplomatic means by which the missing lady, who lived in Bremen as Miss Montague, could be traced.

The two men smoked their cigarettes; Strantz pulling over the switch every five minutes—always to the very tick of the round brass clock—examining the tiny point of light which resulted, and carefully registering the exact amount of current and the position of the ship engaged in paying out the black, insulated line into the bed of the German Ocean.

While Noel watched he also wondered whether, in the near future, that very cable across the sea would be used by England’s enemy for the purposes of her destruction. True, we had our new wireless stations all along the coast, and at other places inland at Ipswich, Chelmsford, and elsewhere, yet if what was feared really came to pass, all those, together with the shore-ends of the cables, would be seized by advance parties of Germans already upon British soil—picked men, soldiers all, who were already living to-day in readiness upon the East Coast of England as hotel-servants, clerks or workers in other trades. Our shrewd, business-like friends across the grey, misty sea would take care to strike a blow on our shores by the wrecking of bridges, the disabling of railways, the destruction of telegraphs, and the like, simultaneous with their frantic dash upon our shore. Germany never does anything by halves, nor does she leave anything to chance.
