“You’ve covered a lot of ground since your daughter’s death was discovered,” Bertha said. “Lawyers, handwriting experts and all that.”

“We did most of it before Mabel’s body was discovered. I felt certain Everett had murdered her. I’ve been certain ever since yesterday morning. Therefore, I’d already started to take steps to see that Everett didn’t get away with anything or profit by his crime — and we’re really indebted to you, Mrs. Cool, for your work in discovering the body.”

“Nothing at all,” Bertha said hastily. “I might be able to uncover more facts for you if—”

“Our lawyer,” Mrs. Goldring interrupted smoothly, “says we have all the facts we need, if we can just get the witnesses to swear to them.”

“Well, he should know.”

“But, Mrs. Cool, can’t you testify there was a fire—”

“I’m afraid not. I make a terrible witness and I’m allergic to lawyers.”

“Our attorney said we could serve a subpoena on you and then you’d have to come to court. He thought it would be better to have a friendly chat with you first.”

“My memory,” Bertha apologized, “is terrible. Right now, I can’t remember a thing about whether there was a fire in Everett Belder’s office. Of course, it may come back to me.”

Mrs. Goldring arose from her chair, distantly formal. “I’m sorry, Mrs. Cool. I had hoped that we could get your testimony without having to serve a subpoena on you.”
