Dr. Maclean’s eyes flamed with anger. “I hope to God that neither my niece nor Harry Garlett will ever see this vulgar, hateful letter.”

“I can reassure you on that point,” said the other earnestly. “Under no consideration are these kinds of communications brought into a law case,” and, as he saw a shadow pass over the doctor’s face:

“Not that I think there will be a law case. Since my talk with Mr. Garlett this morning, and with you during the last hour, I believe that all this trouble has been caused by some hysterical woman who has a grudge against Mr. Garlett.”

Dr. Maclean muttered: “I only wish I had the writer of this letter here.”

“Perhaps you’d rather not see the other letter?” said his visitor, half smiling.

“Of course I’d rather see it!” he exclaimed brusquely, and the police inspector put it down before him.
