"Yes, that was my cousin's eighteenth birthday. We thought if my uncle had left the box in anyone's charge he would probably have given him some such instructions, for at that time there was hard fighting in India, and he might have been killed any day, and would therefore naturally have made some provisions for preventing the secret dying with him."

"I am one of his executors," Mark said; "Mr. Prendergast, the lawyer, is the other. I think I had better go round to him tomorrow and open the letter there."

"Oh, I should think you might open it at once, Thorndyke. It will probably only contain instructions, and, at any rate, as you have the coin and the word, you could come round tomorrow morning and get the chest out if you want it."
