"Enter!" she cried.

The door opened and a hall-boy came in.

"Did you ring, Miss La Croix?" he asked.

"Yes," she replied. "I want you to do something for me."

Rising to her feet she drew the boy aside and held a whispered talk with him for several moments.

In the course of their conversation he said to her:

"I saw two men enter this room just before you came in with that lady and gentleman, and they didn't go out again, either."

The girl looked startled.

She spoke to him rapidly a moment, and he started for the door.

Before he could depart, however, the closet door flew open with a bang and the Bradys sprang from their place of concealment.
