"Stop," he said, "I want to speak to you."

Jack stopped in sheer surprise, and looked at the speaker in wonder. What could the man want with him? At a glance he saw the man was not English, though upon closer examination he could not place the type. The stranger's skin was darker than an Englishman's, but not darker than many a Spaniard's. His eyes were large and black and liquid; their look was now crafty and a trifle menacing; his hair was lank and intensely black. In build he was very slight, with thin arms and legs. Jack's idea was that if he had been a little darker he might very well have been a Hindoo.

"And what, my friend, may you want with me?" said Jack genially.

"This morning you received a letter from your father," said the dusky stranger.

"How under the sun do you know that?" asked Jack; "and what if I did? I don't see where your interest comes in."

"I wish to see that letter. You had better hand it over at once."

"Don't you ever apply for a further stock of cheek, my little man," said Jack, "for you've got all you need, and a little bit over."

"The letter is almost certainly in your pocket," said the stranger in perfect English, yet pronounced with a curiously odd lisp and click, "and I must see it."

"It's in my pocket all right, confound your cheek," replied Jack, "and there it will stay. Come, get a move on you, and clear out of my way."

"I shall not get out of your way," said the other. "I shall stop you until I have read the letter."
