Elaine checked herself. She had been about to hand the note to Del Mar when an idea seemed to come to her. Instead, she crumpled it up and thrust it into her bosom.

On the street the bolero and the domino girl were hurrying away as fast as they could.

Meanwhile, the gray friar had overcome Del Mar, had bound and gagged him, and trust him into the closet. Then he wrote the note and laid it, with a rose from a vase, on Elaine's dressing-table before he, too, followed.

More than ever I was at a loss to make it out.

It was the day after the masquerade ball that a taxicab drove up to the Dodge house and a very trim but not over-dressed young lady was announced as "Miss Bertholdi."

"Miss Dodge?" she inquired as Jennings held open the portieres and she entered the library where Elaine and Aunt Josephine were.

If Elaine had only known, it was the domino girl of the night before who handed her a note and sat down, looking about so demurely, while Elaine read:

MY DEAR MISS DODGE,

The bearer, Miss Bertholdi, is an operative of mine. I would appreciate it if you would employ her in some capacity in your house, as I have reason to believe that certain foreign agents will soon make another attempt to find Kennedy's lost torpedo model.
