Now a door across the hall opened and another figure appeared. Grace trembled for a moment, fearing it might be another thief. She had always heard they traveled in pairs. But it was David, wrapped in a long gray dressing gown, looking for all the world like a monk.
He glanced up and down the hall for a moment, then tapped on the door of the next room and without waiting for an answer walked in. In an instant he was out again and had started swiftly down the stairs, Grace following him. She had intended to speak to him, but it had all taken place so quickly there was no time. David made straight for the dining room, opening the heavy door. The room was brightly lighted. In a flash, Grace saw on the table a pile of the beautiful Gray silver, brought over from England by past generations of Grays. Grace never knew what instinct prompted her to enter the dining room by the butler's pantry at the very end of the long hall. As she pushed the swinging door, she heard David say:
"You low blackguard, what do you mean by stealing your aunt's silver?"
Grace started at the mention of the word "aunt." It was, then, the wretched Tom Gray who was robbing his own relative!
"Get out!" returned the other coldly, "and attend to your own business. You are only a kid."
"Give up those things you have stolen, or I'll pound you to a jelly!" cried David, making a rush at the burglar, who dodged nimbly.
Then Grace had an inspiration, which assuredly saved David from very disagreeable consequences. Real burglars, like rattlesnakes, are not likely to be dangerous except when they are disturbed. It is then that they become dangerous characters. Grace slipped back into the pantry, swiftly opened one of the linen drawers and drew forth what turned out later to be a breakfast cloth, which was lucky because it was small and easy to manage.
When, in the next instant, she had pushed the door open, what she saw made her blood run cold. Tom Gray had whipped out a small pistol and pointed it straight at David's head.
"Get out of here, quick!" he said just as Grace opened the table cloth with a jerk and flung it over his head. A pistol shot rang out, but David had dodged in time and the bullet was buried in the mahogany wainscot back of him. The astonished burglar dropped the weapon, and began to struggle violently to release himself.
Instantly David pinioned his arms from the back. But the fellow might even then have struggled free, if Reddy Brooks and Hippy Wingate had not burst into the room, followed by Anne, who had roused them after Grace had gone. The three boys swiftly overpowered Tom Gray and tied him to a chair with cord Grace had found in the pantry.
