All went merrily indeed, except that Jane was almost lost in bewilderment before she and Teddie had finished out two dances (halves) and one "sitting out" in the Bosky Dell.

Who was this boy's relation? she wanted to know. And why did Sally so promptly surrender him to all other partners? Sally danced so gracefully, and they seemed to step together as dancers do who have learned at the same functions, yet she did surrender him willingly.

Jane dragged Judith out of the din, and after fortifying herself and her chum with two drinks of fruit punch, she dragged her further into semi-seclusion in the cloak room.

"What do you make of it?" asked Judith fairly twittering with suppressed excitement.

"That is what I wanted to ask you," replied Jane, swirling her scarf over her shoulders to tame down a frolicsome little breeze that danced to the jazz music stealing in the cloak room. "There is a positive mystery about all this. Can't you see how much Ted Barrett looks like Sally Howland?"

"Of course I can," replied Judith. "But surely that letter said 'sister' and was written to Shirley."

"And he is not in any way like Bobbie."

"No, and Bobbie is as shy as a baby when speaking with him." Jane bit her lip in serious reflection.

"But isn't he very nice?"

"Lovely manners and a very takable boy," admitted Jane. "And say, Judy, I love this mystery, but we can't let the freshies beat us at it. Be sure you keep your eyes and ears open and report anything— suspicious."
