A THANKSGIVING INVITATION "At last!" exclaimed Grace triumphantly, as she extracted a letter from the Wayne Hall bulletin board addressed to her in Mabel Ashe's unmistakable handwriting.

"Oh, I am so glad! I thought she had forgotten me." "Or had been persuaded to forget you," put in Elfreda Briggs, who had come downstairs to breakfast directly behind Grace.
Grace looked frankly amazed.

"How did you know ?" "How do I find out everything I know ?" demanded Elfreda.

"Don't you suppose I noticed that you were worried about not hearing from Mabel?
I could see you thought some one had made mischief." "Elfreda Briggs, will you please tell me your exact method of deduction!" exclaimed Grace in a half vexed tone.

"Your ability for 'seeing things' is positively uncanny." "There was nothing very uncanny about seeing you look ready to cry every time Mabel's name was mentioned," retorted Elfreda.
