The porter was "downed," and the two detectives talked on other matters for an hour.
Old Broadbrim detailed the crime on Fifth Avenue, and did not forget to mention the murder of Jason Marrow in the little house near the mouth of the alley.
Tom Owens was of the opinion that both crimes were the work of the same hand, and that the tenant of the alley was killed to keep him silent regarding a secret which he undoubtedly possessed.
"You're on the right trail, Broadbrim," said the Englishman. "This Rufus Redmond, alias Merle Macray, is the very person you want, and we'll see that your trail ends right here in London."
In a short time the two detectives sauntered from the room, and Tom Owens guided the American to a certain part of the city, where he had located Rufus Redmond.
"When does the next steamer depart for Melbourne, or for that part of the globe?" anxiously inquired the American detective.
"One leaves to-day," was the reply. "I happen to know, because one of my friends is going out in her and he gave me good-by this morning."
"Why not see if our friend, the murderer, is to be a passenger?"
Tom Owens looked a little astonished by this suggestion.
"It's all right. He will be in London after the Intrepid has sailed," said he. "He is installed in the little red house yonder, and we can lay hands on him whenever we care to."
