"I dare tell you nothing," she said. "The oath binds me; and it binds every one of my kindred to kill me if I break it."

"But you've no kindred left except Constantine," I objected.

"He is enough. He would kill me."

"Sooner than marry you?" I suggested, rather maliciously.

"Yes, if I broke the oath."

"Hang the oath!" said I, impatiently. "The thing might help us. Did they bury Stefan somewhere under the house?"

"No, he was not buried," she answered.
