“Yes, sir.” The woolly-headed one rolled his eyes in enjoyment of his sudden importance. “I knows he did, kase I watched after him.”

“Why did you look after him?”

“No reason, p’tikler. Only kase he’s such a fine gentleman. I most allus looks at him march down the hall. He marches like a—a platoon.”

“He does? And he marched straight to his room?”

“Yessuh.”

“When did you bring him down again?”

“’Bout an hour later, all dressed up in his glad raggses. Just like he is now.”

“Just so. Now, during that hour do you know that Mr Pollard didn’t leave his room? Didn’t go down stairs again?”

“Not in my car, he didn’t. And he always uses my car.”

“Ask the other boy.” Prescott gave this order shortly. The scene was getting on his nerves. Pollard, quiet, calm, but superior. The clerk, ready to enjoy the detective’s discomfiture, if he failed to prove the point he was evidently trying hard to make. Black Bob, the elevator boy, his white teeth all in evidence, and his admiration for Pollard equally plain to be seen. And even the telephone girl, smirking from her switchboard nearby.
