"I am at your service, m'sieur," the other replied in French, motioning him to a chair.

The Count, seating himself, tossed his hat carelessly upon the table, explaining that he had been sent by the Russian Intelligence Department as bearer of certain important documents which would materially assist him in his operations.

"Yes," observed the Prince, "I received a telegram from the Ministry at Petersburg before I left Christiansand, telling me to await you here, and that you would furnish various information."

"That I am ready to do as far as lies in my power," replied the Count, taking from his hip pocket a bulky packet, sealed with three great daubs of black wax. This he handed to the Prince, saying, "It contains maps of the country between Edinburgh and Glasgow, specially prepared by our Secret Service, together with a marked chart of the Firth of Forth, and full detailed information regarding the troops remaining to defend this district."

The Admiral broke the seals, and glanced eagerly through the contents, with evident satisfaction.

"Now, what is the general condition of the south of Scotland?" the Prince asked, lounging back, twirling his moustache with a self-satisfied air.

"Totally unprepared. It is not believed that any attack will be made. The military left north of the Cheviots after mobilisation were sent south to assist in the defence of Manchester."

"Let us hope our expedition to-night will meet with success. We are now one mile east of Craig Waugh, and in an hour our big guns will arouse Leith from its lethargy. You will be able to watch the fun from deck, and give us the benefit of your knowledge of the district. Is the fort at Leith likely to offer any formidable resistance?" continued the Admiral. "I see the information here is somewhat vague upon that point."

"The place is useless," replied the spy, as he stretched out his hand and took a pencil and paper from the Prince's writing-table. "See! I will sketch it for you. In the character of a starving workman who desired to volunteer I called there, and succeeded in obtaining a good view of the interior. They have a few modern guns, but the remainder are old muzzleloaders, which against such guns as you have on board here will be worse than useless." And as he spoke he rapidly sketched a plan of the defences in a neat and accurate manner, acquired by long practice. "The most serious resistance will, however, be offered from Inchkeith Island, four miles off Leith. There has lately been established there a new fort, containing guns of the latest type. A plan of the place, which I succeeded in obtaining a few days ago, is, you will find, pinned to the chart of the Firth of Forth."

The Admiral opened out the document indicated, and closely examined the little sketch plan appended. On the chart were a number of small squares marked in scarlet, surrounded by a blue circle to distinguish them more readily from the dots of red which pointed out the position of the lights. These squares, prepared with the utmost care by von Beilstein, showed the position of certain submarine mines, a plan of which he had succeeded in obtaining by one of his marvellous master-strokes of finesse.
