Intelligence Department was the reverse of comforting. He had known of the arrest of Otto Hartwig, alias Hart, who had, for many years before the war, carried on business in Kensington, but this was the first he had learnt that anything had been found upon the prisoner. He endeavoured to gain some further details from Trustram, but the latter had but little knowledge. "All I know," he said, "is that the case occupied poor Jerrold fully a month of patient inquiry and watchful vigilance. At last his efforts were rewarded, for he was enabled to follow the man down to Portsmouth, and actually watch him making inquiries there--gathering facts which he intended to transmit to the enemy."

The well-dressed man lolling in his chair, smoking as he listened, made a mental note of those names, and grinned with satisfaction at Trustram's indiscretions. Yet, surely, the Admiralty official could not be blamed, for so completely had Lewin Rodwell practised the deception that he believed him to be a sterling Englishman, red-hot against the enemy and all his knavish devices. "I suppose you must be pretty busy at the Admiralty just now--eh? The official account of the Battle of the Falklands in to-night's papers is splendid reading. Sturdee gave Admiral von Spee a very nasty shock. I suppose we shall hear of some other
