"He belongs to our disreputable neighbor, Antonio Ranzetti," she replied, "an Italian animal trainer, who rented and took possession, much against our wishes, of that old brick house in the hollow. Rene would have bought the place, had we known, rather than suffer the annoyance of living next to a menagerie."

"Is it as bad as all that?"

She nodded. "He has a large collection of wild animals in the house and outbuildings, which he is training for the circus," she explained, "and he's just about as secretive in his work as Rene in his scientific researches. He's one of the most expert animal trainers in the world, I believe."

Then she suddenly remembered the book I was after. "I'm sure my husband did not keep your brother's book intentionally," she said. "He's very forgetful of what he calls trivialities." She walked over to a disordered desk, and with a sharp exclamation, picked up the book from among a row of volumes on top of it. "There you are!" she said.

My back was turned towards the door into the hall as I took the book, and expressed my thanks for its return. I was just on the point of departure, seeing I had no further excuse to remain on the premises, when I saw her start, and turn pale. Turning round quickly, I faced Dr. LaRauche, as he entered the library. In looks, he was about the angriest looking man I had ever encountered.

"Ah, Dr. LaRauche!" I said, without turning a hair.

He made no reply, just stood there, glaring, and inspecting me from top to toe. Finally, he spoke. "I know what's brought you here, Livingston Royce," he said. "I expected it."

Coming out of her cowering fright, and finding her voice, Mrs. LaRauche broke in falteringly. "Mr. Royce came after the Lowell book on Mars you borrowed from his brother, Henry, more than—"

A contemptuous exclamation cut her short. "Something more than the borrowed book brought him here," LaRauche said.

"What, for instance?" I asked him, point-blank.
