"I waitin' for—"
"Go away!"
Isaacson had never before spoken so roughly, so almost ferociously to a dependant. When Hassan had gone, ferociously Isaacson opened the letter. It was not very long, and his eyes seized every word of it almost at a glance—seized every word and conveyed to his brain the knowledge, undesired by him, that the detective had been right.
"Loulia, Nile, Wednesday.
"Dear Doctor,
"I find it is better not. When I came on board again I found Nigel reading over one of the notices of Harwich's death. I had begged him to put them away, and not to brood over the inevitable. (We only got the papers giving an account of Harwich yesterday.) But being so seedy, poor boy, I suppose he naturally turns to things that deepen depression. I ought not to have left him. But he insisted on my taking a ride and visiting the temple, which I had never been in before. I persuaded him to put away the papers, and am devoting myself to cheering him up. We play cards together, and I make music, and I read aloud to him. The great thing is—now that he has taken a decided turn for the better—not to excite him in any way. Now you, dear doctor—you mustn't mind my saying it—are rather exciting. You have so much mentality yourself that you stir up one's mind. I have always noticed that. Fond as he is of you, just at this moment I fear you would exhaust Nigel. He gets hot and excited so easily since the sunstroke. So please pass us by without a call, and do be kind and wait for us at Assouan. In a very few days we shall be able to receive you, and then, when he is a little stronger, you can be of the greatest help to Nigel. Not as a doctor—you see we have one, and mustn't leave him; medical etiquette, you know!—but as a friend. It is so delightful to feel you will be at Assouan. If you are the least anxious about your friend, when you get to Assouan ask for Doctor Baring Hartley, if you like, Cataract Hotel. He will set your mind at rest, as he has set mine. It is only a question of keeping very quiet and getting up strength.
"Sincerely yours,
"Ruby Armine.
"P.S. Don't let your men make too much noise when passing us. Nigel sleeps at odd times. Perhaps wiser to pole up along the opposite bank."
