Miss Cornelia made up her mind. She had resolved before not to summon the Doctor for aid in her difficulties, but now that chance had brought him here the opportunity seemed too good a one to let slip.

"Doctor," she said, "I think I ought to tell you something. Last night and the night before, attempts were made to enter this house. Once an intruder actually got in and was frightened away by Lizzie at the top of that staircase." She indicated the alcove stairs. "And twice I have received anonymous communications threatening my life if I did not leave the house and go back to the city."

Dale rose from her settee, startled.

"I didn't know that, Auntie! How dreadful!" she gasped.

Instantly Miss Cornelia regretted her impulse of confidence. She tried to pass the matter off with tart humor.

"Don't tell Lizzie," she said. "She'd yell like a siren. It's the only thing she does like a siren, but she does it superbly!"

For a moment it seemed as if Miss Cornelia had succeeded. The Doctor smiled; Dale sat down again, her expression altering from one of anxiety to one of amusement. Miss Cornelia opened her lips to dilate further upon Lizzie's eccentricities.

But just then there was a splintering crash of glass from one of the French windows behind her!
