Joan slid her chair up until her red plaid skirt touched the gray-trousered knees of Mr. Albert Johnson. His cane was leaning back against his arm now. She told him all about the Dummy—how the copy must have been changed, and Dummy had insisted that it had been handed to him like that, when she knew she hadn’t written it wrong.

Then she went on and told him how she and Chub and Amy had jumped to the conclusion that Dummy was a spy. “Every crime has a motive, you know,” she assured him earnestly. “And so we thought it all out. Of course, we’ll have to have more evidence than just that before we can accuse him.”

“Of course,” nodded Albert Johnson. “Now, listen here. I’m part owner here and I’ll fix it for your brother to stay on here, and for you to stick around this office as much as you like, on one condition.”

“Yes, indeed.” Joan felt she would promise anything to save Tim.

“I want you to promise me to watch out for ‘developments’ as you call them, and come to me the next time anything suspicious happens. I don’t mind admitting things look queer. And don’t you accuse any one until you come to me. Remember?”

That would be easy! They were going to watch for developments, anyway. And Tim’s job would be safe.

Mr. Johnson got Tim back to the desk, and shook his hand, before he went into Uncle John’s little office with the frosted glass door and the “John W. Martin” on it. Joan watched his bulldog profile shadowed there until Mother telephoned to Tim to “send Joan home to help with dinner.” Amy had left long ago.

Nothing very exciting happened anyway, Joan learned later. Uncle John had been on the verge of firing Tim, but after his talk with Mr. Johnson, he said Tim could remain on probation, providing no more mistakes happened. That evening, Tim spent hours wording an apology concerning Mr. Johnson for the paper, and Joan insisted that he tell the public what a nice man Mr. Johnson was.

Tim told her that Mr. Johnson was a wealthy man who dabbled in politics as a pastime, so she understood how he had time to bother with mysteries. The Journal staff would be interested in it, but they were all too busy to do much more than wonder. She did not tell any one that she had enlisted Mr. Johnson’s services in the detective work.

Tim’s write-up of Mr. Johnson must have met with his approval, because he telephoned Joan about twenty minutes after the paper was out, that he was about ready to forgive the entire affair. He asked Joan whether she were watching out for the mystery.
