"I have letters to write." "I'll go," agreed Grace.
Elfreda alone was silent.
"And what has J.Elfreda Briggs on her mind ?" questioned Anne.
"I can't go.

I have another little investigation to pursue," said Elfreda pompously.

"If it turns out well, I may have something to tell you girls." But that night, when the four chums gathered in Grace's room for a brief social session before retiring, Elfreda shook her head soberly when reminded of her partial promise.

"I am sorry, but I didn't say positively that I'd tell you." "Then it didn't turn out well ?" from Miriam.
"No," replied Elfreda shortly, "it didn't." Three pairs of eyes were fixed inquiringly upon Elfreda.

"I didn't promise to tell you anything, you know," she reminded bluntly.
"We are well aware of that fact, my dear Miss Briggs," laughed Miriam, "but we would appreciate your confidence, and having aroused our curiosity you ought to do something to satisfy it." "All right, I'll tell you," decided Elfreda.
