The trio did not breathe.

The footsteps paused before the sitting-room door.

The confederates gripped each others' arms.
"Are you sure you saw that person come in here ?" they heard a voice ask--Jack's voice.
"I'm certain." The voice that answered was Mary's.
"I'll bet it was a sneak thief," said a third voice--Mr.Pyecroft's.
"To slip into a house at a funeral, or a wedding, when a lot of people are coming and going--that's one of their oldest tricks." He turned the knob, and finding the door locked, shook it violently.

"Open up, in there!" he called.
The three clung to one another for support.
"Better open up!" called a fourth voice--Judge Harvey's.

"For we know you're in there!" Breathless, the trembling conspirators clung yet more desperately.
"But how could she get in ?" queried the excited voice of Mary.
