When the moment was opportune, Miss Chalmers proposed to steal it. Of course she could never wear it again in the presence of the Witherbees or any of their guests; but she would possess it at any rate.

Breakfast was served on a broad porch at the rear of the house, which was the Witherbees' dining-room for all meals when the weather was fine. It was not yet finished when Miss Chalmers saw something as she glanced beyond the railing that fascinated her.

She stared fixedly, then brought her glance suddenly back to the table and furtively examined the faces of her hosts and fellow guests. After that she looked over the railing again. If she grew a shade paler, nobody appeared to observe the fact; nor did any one notice she had become restless.

After a minute or two she rose and walked toward the steps. They descended to a lawn that was broken with shrubs and flower-beds and paths.

"Where away, Rosalind?" called Gertrude.

"I want to see the garden," she called back.

But instead of making directly for the garden she followed a course closely parallel to the porch, which brought her to a pathway that led from a rear door of the house to a small outbuilding that served as a summer kitchen.

"Wait! Stop, Rosalind!"

She did not seem to hear, but stepped upon the path.

"You'll ruin your shoes!" cried Mrs. Witherbee.
