We had once more turned into John Street and now perceived a man, standing on the wide doorstep of the house with the shattered window, looking anxiously up and down the street.
"Do either of you gents know anything about this here?" he asked, pointing to the broken pane.
"Yes," said Thorndyke, "we happened to be passing when it was done; in fact," he added, "I rather suspect that the missile, whatever it was, was intended for our benefit."
"Oh!" said the man. "Who done it?"
"That I can't say," replied Thorndyke. "Whoever he was, he made off on a bicycle and we were unable to catch him."
"Oh!" said the man once more, regarding us with growing suspicion. "On a bicycle, hay! Dam funny, ain't it? What did he do it with?"
"That is what I should like to find out," said Thorndyke. "I see this house is empty."
"Yes, it's empty—leastways it's to let. I'm the caretaker. But what's that got to do with it?"
"Merely this," answered Thorndyke, "that the object—stone, bullet or whatever it may have been—was aimed, I believe, at me, and I should like to ascertain its nature. Would you do me the favour of permitting me to look for it?"
The caretaker was evidently inclined to refuse this request, for he glanced suspiciously from my companion to me once or twice before replying, but, at length, he turned towards the open door and gruffly invited us to enter.
