As they entered the room beyond, a fierce growl was heard.
"Let me go first," said Blueskin; "the dogs know me. Soho! boys." And, walking up to the animals, which were chained to the wall, they instantly recognised him, and suffered the others to pass without barking.
Groping their way through one or two dark and mouldy-smelling vaults, the party ascended a flight of steps, which brought them to the hall. As Jack conjectured, no one was there, and, though a lamp was burning on a stand, they decided upon proceeding without it. They then swiftly mounted the stairs, and stopped before the audience-chamber. Applying his ear to the keyhole, Jack listened, but could detect no sound. He, next cautiously tried the door, but found it fastened inside.
"I fear we're too late," he whispered to Thames. "But, we'll soon see. Give me the chisel, Blueskin." And, dexterously applying the implement, he forced open the lock.
They then entered the room, which was perfectly dark.
"This is strange," said Jack, under his breath. "Sir Rowland must be gone. And, yet, I don't know. The key's in the lock, on the inner side. Be on your guard."
"I am so," replied Thames, who had followed him closely.
"Shall I fetch the light, Captain?" whispered Blueskin.
"Yes," replied Jack. "I don't know how it is," he added in a low voice to Thames, as they were left alone, "but I've a strange foreboding of ill. My heart fails me. I almost wish we hadn't come."
As he said this, he moved forward a few paces, when, finding his feet glued to the ground by some adhesive substance, he stooped to feel what it was, but instantly withdrew his hand, with an exclamation of horror.
