Moreover, his strength was leaving him. There was an alarming weakness in his legs, purely physical. He had overdone, and if need rose he would not be able to protect her. Damnable fool! But she had known. That was the odd phase of it. She hadn't come blindly. What mood had urged her to share the danger along with the lark? Somehow, she was always just beyond his reach, this girl. He would never forget that fan popping out of the pistol, the egg burning in the pan.

The apartment was only three blocks away when Kitty decided to drop her mask. “I'd give a good deal to see a policeman. They are never around when you really want them. Johnny Two-Hawks, I'm a little fool! You wouldn't have left the apartment but for me. Will you forgive me?”

“It is I who should ask forgiveness. I say, how much farther is it?”

“Only about two blocks; but they may be long ones. Let's step into this doorway for a moment. I see a taxicab. It looks to be standing opposite the building. Don't like it. Suppose we watch it for a few minutes?”

Hawksley was grateful for the respite; and together they stared at the unwinking red eye of the tail light. But no man approached the cab or left it.

“I believe I've hit upon a plan,” said Kitty. “Certainly we have not been followed. In that event they would have had a dozen chances. If someone saw us leave together, naturally they will expect us to return together. We'll walk to the corner of our block, then turn east; but I shall remain just out of sight while you will go round the block. Fifteen minutes should carry you to the south corner. I'll be on watch for you. The moment you turn I'll walk toward you. It will give us a bit of a handicap in case that taxi is a menace. If any one appears, run for it. Where's the cane you had?”

“What a jolly ass I am! I remember now. I left the stick against the wall of the opera house. Blockhead! With a stick, now!... I'm hopeless!”

“Never mind. Let's start. That taxi may be perfectly honest. It's our guilty consciences that are peopling the shadows with goblins. What really bothers us is that we have broken our word to the kindliest man in all this world.”

Hawksley wondered if he could walk round the block without falling down. He saw that he was facing a physical collapse, hastened by the knowledge that the safety of the girl depended largely upon himself. What he had accepted at the beginning as strength had been nothing more than exhilaration and nerve energy. There was now nothing but the latter, and only feeble straws at that. Oh, he would manage somehow; he jolly well had to; and there was a bare chance of falling in with a bobby. But run? Honestly, now, how the devil was a chap to run on a pair of spools?

Arriving at the appointed spot they separated. He waved his hand airily and marched off. If he fell it would be out of sight, where the girl could not see him. Clever chap—what? Damned rotter! For himself he did not care. He was weary of this game of hide and seek. But to have lured the girl into it! When he turned the first corner of his journey he paused and leaned against the wall, his eyes shut. When he opened them the sidewalk and the street lamps were normal again.
