“How do you happen to know him, sir?”

“Arnesson has brought him to the house here several times. Wanted me to see him and talk to him. Arnesson was quite proud of the boy; and I must admit he showed unusual talent.”

“Then he was known to all the members of the household?”

“Yes. Belle met him, I think. And if by ‘the household’ you include Pyne and Beedle, I should say the name was probably familiar to them too.”

Vance asked the next question.

“Did the Drukkers know Sprigg, Professor Dillard?”

“It’s quite possible. Arnesson and Drukker see each other a great deal. . . . Come to think of it, I believe Drukker was here one night when Sprigg called.”

“And Pardee: did he also know Sprigg?”

“As to that I couldn’t say.” The professor tapped impatiently on the arm of his chair, and turned back to Markham. “See here”—his voice held a worried petulance—“what’s the point of these questions? What has our knowing a student named Sprigg to do with this morning’s affair? Surely you don’t mean to tell me that the man who was killed was Arnesson’s pupil.”

“I’m afraid it’s true,” said Markham.
