After the girls had finished washing the dishes for Mrs. Gay, they started off for a little walk, with Silky at their heels.

“Why not stop for the Reed girls?” suggested Jane, mentioning the twins who lived in the cottage on the far side of the Gays. “I’m crazy to meet them.”

“You’ll meet them when we go swimming later on,” replied Mary Louise. “But just now I want to go in the other direction. To call on the Ditmars.”

“The Ditmars?” For the moment Jane had forgotten who these people were, for she had heard so many new names the night before.

“Yes. Don’t you remember? The young architect that Cliff told us about. The man Mrs. Hunter thinks set her bungalow on fire.”

“Oh, yes, of course! In other words—a suspect.”

“That’s right,” agreed Mary Louise.

“But how can we call on him if we don’t know him?” asked Jane.

“We’ll find a way!”

“Oh, sure we will!” teased Jane. “Trust the girl detective for that!”
