“It is scarcely possible——” Dr. Whitlett began.

“Don’t lie, sir!” the admiral thundered out. “You are a pack of fools and old women! You are as ignorant as rabbits! You know no more than the kitchenmaids what has been growing and growing within these walls. I tell you that my work of the last few years, placed in certain hands, would alter the whole face of Europe—aye, of Christendom! There are men in this country to-day whose object is to rob me, and you, my own household, seem to be crying them welcome, bidding them come and help themselves, as though the labour of my life was worth no more than so many sheets of waste paper. You have let a stranger into this room to-day, and if he had not been disturbed, God knows what he might not have carried away with him!”

“We have been very foolish,” Lady Deringham said pleadingly. “We will set a watch now day and night. We will run no more risks! I swear it! You can believe me, Horace!”

“Aye, but tell me the truth now,” he cried. “Some one has been in this room and escaped through the window. I learnt as much as that from that blithering idiot, Blatherwick. I want to know who he was?”

She glanced towards the doctor. He nodded his head slightly. Then she went up to her husband and laid her hand upon his shoulders.

“Horace, you are right,” she said. “It is no use trying to keep it from you. A man did impose upon us with a forged letter. He could not have been here more than five minutes, though. We found him out almost at once. It shall never happen again!”

The wisdom of telling him was at once apparent. His face positively shone with triumph! He became quite calm, and the fierce glare, which had alarmed them all so much, died out of his eyes. The confession was a triumph for him. He was gratified.

“I knew it,” he declared, with positive good humour. “I have warned you of this all the time. Now perhaps you will believe me! Thank God that it was not Duchesne himself. I should not be surprised, though, if it were not one of his emissaries! If Duchesne comes,” he muttered to himself, his face growing a shade paler, “God help us!”

“We will be more careful now,” Lady Deringham said. “No one shall ever take us by surprise again. We will have special watchmen, and bars on all the windows.”

“From this moment,” the admiral said slowly, “I shall never leave this room until my work is ended, and handed over to Lord S——’s care. If I am robbed England is in danger! There must be no risks. I will have a sofa-bedstead down, and please understand that all my meals must be served here! Heggs and Morton must take it in turns to sleep in the room, and there must be a watchman outside. Now will you please all go away?” he added, with a little wave of his hand. “I have to reconstruct what has been stolen from me through your indiscretion. Send me in some coffee at eleven o’clock, and a box of cartridges you will find in my dressing-room.”
