“Yes. A big fellow has been down here once or twice. He’s going out as the manager, I guess. His name was—let me see now—”

“Voles?” suggested Steingall.

“No, that wasn’t it. Oh, I’ve got it—Vane, it was.”

Carshaw, dreadfully impatient, failed to understand all this preliminary survey; but the detective had no warrant, and ship’s captains become crusty if their vessels are boarded in a peremptory manner without justification. Moreover, Steingall quite emphatically ordered Carshaw to remain on the wharf while he and others went on board.

“You want to strangle Voles, if possible,” he said. “From what I’ve heard of him he would meet the attempt squarely, and you two might do each other serious injury. I simply refuse to permit any such thing. You have a much more pleasant task awaiting you when you meet the young lady. No one will say a word if you hug her as hard as you like.”

Carshaw, agreeing to aught but delay, promised ruefully not to interfere. When the river police were at hand a nod brought several powerfully built officers closing in on the main gangway of the Wild Duck. The police-captain, in uniform, accompanied Steingall on board.

A deck hand hailed them and asked their business.

“I want to see the captain,” said the detective.

“There he is, boss, lookin’ at you from the chart-house now.”

They glanced up toward a red-faced, hectoring sort of person who regarded them with evident disfavor. Some ships, loading for Central American ports at out-of-the-way wharves, do not want uniformed police on their decks.
