David and Mary Louise sat still, looking at each other in speechless wonder, not knowing whether to laugh or to cry at the poor deluded woman.

“But she seems happy,” remarked David. “So I guess we needn’t pity her.”

“She’s like that bride in the Dickens book,” said Mary Louise. “The woman who was deserted on her wedding day and wore her wedding dress all the rest of her life, expecting her bridegroom to come back. Remember? That always gave me the creeps.”

“But this woman is happier. She’s sure she’s going to meet her Isaac at a well.” He laughed. “No, I think we’re more to be pitied than she is. For if she goes around setting fire to people’s places——”

“She ought to be locked up! Yet that seems a shame, if she does happen to be harmless.” Mary Louise stepped on the starter. “Well, let’s go on up to the Adams’. Maybe they can tell us who she is.”

They continued on up the hill to the farm and left the car at the entrance to the front yard, just outside the picket fence. The Adams place was a neat-looking frame house, painted white, and pleasant to look at. A big porch surrounded it on all sides, and here they saw Hattie Adams, seated in a rocking chair, sewing. She waved to Mary Louise.

“Hello, folks!” she called genially. “Come on up! Any news?”

“No, we haven’t,” replied Mary Louise as she sat down. “But I did want to ask you what you knew about the fire, Hattie, because Mr. Flick is sort of blaming my brother and the other small boys, and I know they didn’t start it. So will you tell us when you left Flicks’—and all you know about it?”

Hattie nodded solemnly.

“Well, let me see,” she began. “We had supper at half-past five last night, didn’t we? And everybody was through eatin’ about quarter to seven. Even Mis’ Flick. The other two hired girls helped me wash some of the dishes, and then Mr. Flick drove ’em over to the Junction. He come back for Mis’ Flick about half-past seven, I reckon. They put the car away and went to the picnic in a boat. I was just finishin’ washin’ dishes.”
