A door under the stairs gave on steps leading to the cellar. A gaslight had been left burning down here. They saw the furnace that supplied the heat, but there was no person in the cellar.
Greg left Bull on guard on the basement floor. "If anybody gets past us up-stairs, don't let him get by you without frisking him for the book. If they come too fast for you, call for help."
Greg and Estuban stole up to the main floor. Two long parlors front and rear opened off the hall. They were dusty and empty like the rooms below. At the head of the next flight of stairs a crack of light showed under a door, and a murmur of voices came down to them.
Greg whispered to Estuban: "Creep up stairs and listen. It may be valuable to us. I'll call the other men in."
With infinite caution Greg unchained and unlocked the two sets of doors and stepped out on the stoop. The block was empty. But there were eyes out. For when Greg gave the prearranged signal three figures appeared from the shadows opposite and noiselessly hastened to him. He drew them inside the house and shut the doors.
Hickey was sent to help Bull because there were two ways out from the basement to be watched; Blossom was left at the front door; Greg and Ginger stole on up and joined Estuban at the turn of the stairs. Putting his lips to Greg's ear Estuban breathed:
"We're just in time. They're breaking up here. There are not more than four men with de Socotra in there. The rest have already scattered. He's giving these their final instructions now."
Greg whispered back: "Is the door locked?"
"I don't think so. There's no key in the other side. Now that you're here to back me up I'll try the handle."
"Wait a minute. Front and rear bedrooms in these houses usually communicate. Ginger, go in the front room and stand guard. Take my flash."
