"How long did it take you to reach Catchpole Square?"
"It was a dark night, and I should think it took me half an hour or so."
"So that you would be in front of Mr. Boyd's house at about half past two?"
"Yes, sir."
"You knocked more than once?"
"Several times, sir."
"And waited between each fresh summons for an answer?"
"For the answer that never came, sir."
"And after that, you hung about the Square. Can you say for how long a time?"
"I can't speak with certainty, but I should say I must have been there altogether quite an hour."
