“We got it!” Carol burst in followed by Janet.
“Is it catching?” Valerie asked.
“Whose is it?” Gale wanted to know.
“The Chemistry Professor’s,” Carol said proudly.
“And the assistant’s,” added Janet. “We covered them both. Are we good detectives or are we?”
The check-up of the typing on the last two notes was the same as it had been with Marcia’s. None of them were alike and none of them resembled the typing in the mysterious note. The type of the Chemistry Professor’s machine was much larger while that of his assistant was smaller.
“Shucks,” Carol said disgustedly. “We had all that work for nothing.”
“Perhaps it wasn’t written by any machine here at the college,” Valerie said.
Gale nodded. “True, it might not have been.”
“I think it was,” Carol said. “There are no visitors on whom we could blame all these mysterious happenings, and certainly the same person is responsible for the notes!”
