“Read it, and tell me what you think of it.”

Gervase took the paper, and his astonishment deepened as he read:

June 9. Pass the bearer through the lines. He is doing faithful service. Given under our hand. Hamilton.

“Miss Carew, where did you get this? If the man who held this paper be in the city, he is a traitor and a spy, and we should not lose a moment in discovering his villainy.”

“I knew you would use words like these. But there is something more. Three days ago, Mr. Orme, I found this paper on the staircase. Now you know my secret and why I sent for you.”

“Perhaps the Vicomte----” Gervase began.

“Nay, nay, you see the date, and my cousin Victor is still a man of honour. He has given his parole, nor would he break it for the world. It almost breaks my heart to say it, but I feel that this is my brother; I saw him searching for it where I found it, and he would have questioned me about it had he dared. And now I know why he left his room at night and seldom returned before the morning. What is to be done?”
