“You’ll do no such thing, Hugh!” Barbara had recovered her breath. “There’s nothing much the matter with me—at least, I am not sure whether I ought to tell you.”

“Bab and Hugh! Well, I like this!” Grace’s voice sounded from the doorway, as she and Donald Cartwright came in, followed by Ruth and Ralph. “Here you two have run away by yourselves, when we promised to stick together this evening, in order to keep up each other’s courage. You ought to see Gladys! She’s as angry as can he, and is wandering round with Mollie and the freshman. Harry has been gone somewhere for a long time, and she has no partner for the next dance.”

“Are you sick, Bab?” inquired Ruth. She, too, noticed that Bab was unusually pale. Before she received an answer, Governor and Mrs. Post came into the conservatory, followed by Harry Townsend, Miss Stuart and the woman in yellow.

“You are just the fellow I want to see, Hugh,” said his father, so quietly that no one except those near him could hear. “Your mother has lost her emerald necklace, and she thought she had it on when she was last in here. We don’t want to create any excitement, or to let Mrs. Erwin or the servants know until we have made a thorough search. She very probably dropped it among these flowers. Lock the door out there, will you? Miss Carter, you and Donald, please keep guard at the other door while these young people help me look.”

“I thought——” said Barbara.

“Why, you were in here, child, when we were. You were on the other side of these evergreens,” said Mrs. Post. “What did you say?”

“I thought it might be in these evergreens,” Barbara finished, lamely, getting down on her knees to assist in the search. Dared she speak of what she thought she had seen? Dared she speak with no evidence but her own word? Could she have been in error? First, she would look with the others.

Every palm, every flower, every inch of space was carefully gone over. No sign of the missing emeralds!

“Did anyone enter the conservatory after I left, Miss Thurston?” inquired Mrs. Post coldly. She was worried by the loss of her jewels, which were of great value, as well as annoyed by the excitement she was causing.

“Nobody came in,” Bab said, “only Hugh.”
