They came into a double room lined entirely with books, and brilliantly, rather hardly, lit by electricity. The windows at one end looked on to the Park, at the other on to the garden of a neighbouring house. The door by which they entered was concealed from the inner and smaller room by the jutting wall of the outer room, in which stood a huge writing-table loaded with letters, pamphlets and manuscripts. Between the two windows of the inner room was a cage in which a large, grey parrot was clambering, using both beak and claws to assist him in his slow and meditative peregrinations.

"You have a pet," said the Father, surprised.

"I possess a parrot," the Professor answered, drily, "I got him for a purpose when I was making a study of the imitative powers of birds, and I have never got rid of him. A cigar?"

"Thank you."

They sat down. Father Murchison glanced at the parrot. It had paused in its journey, and, clinging to the bars of its cage, was regarding them with attentive round eyes that looked deliberately intelligent, but by no means sympathetic. He looked away from it to Guildea, who was smoking, with his head thrown back, his sharp, pointed chin, on which the small black beard bristled, upturned. He was moving his under lip up and down rapidly. This action caused the beard to stir and look peculiarly aggressive. The Father suddenly chuckled softly.

"Why's that?" cried Guildea, letting his chin drop down on his breast and looking at his guest sharply.

"I was thinking it would have to be a crisis indeed that could make you cling to your butler's affection for assistance."

Guildea smiled too.

"You're right. It would. Here he comes."

The man entered with coffee. He offered it gently, and retired like a shadow retreating on a wall.
