Harry studied Le Blanc, and recognized him as a silent type of man. The fellow had a sophisticated air that commanded instant attention.

“No one here yet,” said Le Blanc tersely, after he had made a quick survey of the crowd below.

HARRY watched the man’s eyes. Joe le Blanc had a faculty for looking everywhere, without moving his head. One observing him from below would not have realized that he had made a thorough inspection of the entire room beneath the balcony.

Four people entered the restaurant — two men in evening clothes, and two handsomely dressed women.

“That’s Glen Colliver,” said Le Blanc, in an undertone. “Big advertising man. Don’t know the fellow with him. Some guy from out of town, I guess.

“That blond dame’s been here before. Never saw the brunette before. The whole bunch is O.K. because Colliver is with them. Remember that bird. He pays plenty here.”

The party had scarcely seated itself before another group entered. Le Blanc recognized them immediately, and gave the information to Harry. Then came a few more persons who were identified by the sharp-eyed watcher.

Finally Colliver and his companions walked up the steps to the balcony. They disappeared behind the pillar that hid the entrance of the gambling den.

“They’ll be looked over through the door,” said Le Blanc. “Old Hawk-eye in there can tell any one that’s been here once. Here comes another pair upstairs. They’re O.K., too.”

Nothing was said for a few minutes. Then Harry decided to question Joe le Blanc.
