"We'll tell her together," he said readily.

"We—perhaps we'd better not tell father," she said with an effort.

The words had scarcely left her lips when a startling interruption came. A heavy body dropped from above, landing in the middle of the sidewalk not more than six feet from the doorway. Vivid flashes of lightning revealed to the couple the figure of a man standing upright before them, but looking in quite another direction. Christine's sharp little cry came as the first flash died away, but another followed in a second's time. The man was now facing the doorway, his body bent forward, his white face gleaming in the unnatural light. David had withdrawn his arms from about Christine and had planted himself in front of her. Pitchy darkness returned in the fraction of a second.

Distinctly they heard a laugh. Then out of the clatter and swish of driven water came the cheerful cry:

"Hello, Jack Snipe!"

"Who are you?" called out David.

"Ha! Who goes there, you mean. Always use the correct question, kid. How can I give the secret password unless you put it up to me right? Oh, I say! I didn't see you, Miss Christine. Geminy! Ain't this a pelter?"

"Why, it's Dick," cried David. "Where in the world did you drop from? The sky?"

The pickpocket laughed gleefully.

"Did I scare you? I guess it must have surprised you, me popping in here like a Punch and Judy figure, eh? You kind o' surprised me, too, I'll say that for you. Gee whiz, I didn't know anybody was here. Say, do you mind if I get back in there out o' the wind to light my pipe? I'm perishin' for a smoke."
