"What are you going to do?" he asked suspiciously.

"I'm wiring Rex to say that you and I are traveling to New York together, and advising him to suspend operations until we arrive. That will be helpful. You will not be tempted to act foolishly, and he will not do anything to prejudice your future actions."

He gave her a wrathful glance. Mrs. Carshaw missed no point. A man driven to desperation might be tempted to bring about an "accident" if he fancied he could save himself in that way. But, clever as a mother scheming for her son's welfare proved herself, there was one thing she could not do. Neither she nor any other human being can prevent the unexpected from happening occasionally. Sound judgment and astute planning will often gain a repute for divination; yet the prophet is decried at times. Steingall had discovered this, and Mrs. Carshaw experienced it now.

It chanced that Mick the Wolf, lying in Gateway House on a bed of pain, his injuries aggravated by the struggle with the detective, and his temper soured by Rachel Craik's ungracious ministrations, found his thoughts dwelling on the gentle girl who had forgotten her own sorrows and tended him, her enemy.

Such moments come to every man, no matter how vile he may be, and this lorn wolf was a social castaway from whom, during many years, all decent-minded people had averted their faces. His slow-moving mind was apt to be dominated by a single idea. He understood enough of the Costa Rican project to grasp the essential fact that there was money in it for all concerned, and money honestly earned, if honesty be measured by the ethics of the stock manipulator.

He realized, too, that neither Voles nor Rachel Craik could be moved by argument, and he rightly estimated Fowle as a weak-minded nonent.i.ty. So he slowly hammered out a conclusion, and, having appraised it in his narrow circle of thought, determined to put it into effect.

An East Orange doctor, who had received his instructions from the police, paid a second visit to Mick the Wolf shortly before the hour of Mrs. Carshaw's arrival in Atlantic City.

"Well, how is the arm feeling now?" he said pleasantly, when he entered the patient's bedroom.

The answer was an oath.

"That will never do," laughed the doctor. "Cheerfulness is the most important factor in healing. Ill-temper causes jerky movements and careless--"

"Oh, shucks," came the growl. "Say, listen, boss! I've been broke up twice over a slip of a girl. I've had enough of it. The whole darn thing is a mistake. I want to end it, an' I don't give a hoorah in Hades who knows. Just tell her friends that if they look for her on board the steamer _Wild Duck_, loadin' at Smith's Pier in the East River, they'll either find her or strike her trail. That's all. Now fix these bandages, for my arm's on fire."

The doctor wisely put no further questions. He dressed the wounded limb and took his departure. A policeman in plain clothes, hiding in a neighboring barn, saw him depart and hailed him: "Any news, Doc?"

"Yes," was the reply. "If my information is correct you'll not be kept there much longer."

He motored quickly to the police-station. Within the hour Carshaw, with frowning face and dreams of wreaking physical vengeance on the burly frame of Voles, was speeding across New York with Steingall in his recovered car. He simply hungered for a personal combat with the man who had inflicted such sufferings on his beloved Winifred.

The story told by Polly Barnard, and supplemented by Petch, revealed very clearly the dastardly trick practised by Voles the previous evening, while the dodge of smearing out two of the figures on the automobile's license plate explained the success attained in traversing the streets unnoticed by the police.

Steingall was inclined to theorize.

"The finding of the car puzzled me at first, I admit," he said. "Now, a.s.suming that Mick the Wolf has not sent us off on a wild-goose chase, the locality of the steamer explains it. Voles drove all the way to the East Side, quitted the car in the neighborhood of the pier, deposited Miss Bartlett on board the vessel under some plausible pretext, and actually risked the return journey into the only part of New York where the missing auto might not be noticed at once. He's a bold rogue, and no mistake."

But Carshaw answered not. The chief glanced at him sideways, and smiled.

There was a lowering fire in his companion's eyes that told its own story. Thenceforward, the run was taken in silence. But Steingall had decided on his next move. When they neared Smith's Pier Carshaw wished to drive straight there.

"Nothing of the sort," was the sharp official command. "We have failed once. Perhaps it was my fault. This time there shall be no mistakes.

Turn along the next street to the right. The precinct station is three blocks down."

Somewhat surprised by Steingall's tone, the other obeyed. At the station-house a policeman, called from the men's quarters, where he was quietly reading and smoking, stated that he was on duty in the neighborhood between eight o'clock the previous evening and four o'clock that morning. He remembered seeing a car, similar to the one standing outside, pa.s.s about 9.15 P.M. It contained two people, he believed, but could not be sure, as the screens were raised owing to the rain. He did not see the car again; some drunken sailors required attention during the small hours.

The local police captain and several men in plain clothes were asked to a.s.semble quietly on Smith's Pier. A message was sent to the river police, and a launch requisitioned to patrol near the _Wild Duck_.

Finally, Steingall, who was a born strategist, and whose long experience of cross-examining counsel rendered him wary before he took irrevocable steps in cases such as this, where a charge might fail on unforeseen grounds, made inquiries from a local ship's chandler as to the _Wild Duck_, her cargo, and her destination.

There was no secret about her. She was loading with stores for Costa Rica. The consignees were a syndicate, and both Carshaw and Steingall recognized its name as that of the venture in which Senator Meiklejohn was interested.

"Do you happen to know if there is any one on board looking after the interests of the syndicate?" asked the detective.

"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.

The two climbed an iron ladder. Men at work in the forehold ceased operations and looked up at them. Their progress was followed by many interested eyes from the wharf. The captain glared angrily. He, too, had noted the presence of the stalwart contingent near the gangway, nor had he missed the police boat.

"What the--" he commenced; but the detective's stern question stopped an outburst.

"Have you a man named Voles or Vane on board?"

"Mr. Vane--yes."

"Did he bring a young woman to this ship late last night?"

"I don't see--"

"Let me explain, captain. I'm from the detective bureau. The man I am inquiring for is wanted on several charges."

The steady official tone caused the skipper to think. Here was no cringing foreigner or laborer to be brow-beaten at pleasure.

"Well, I'm--" he growled. "Here, you," roaring at a man beneath, "go aft and tell Mr. Vane he's wanted on the bridge."

The messenger vanished.

"I a.s.sume there _is_ a young lady on board?" went on Steingall.

"I'm told so. I haven't seen her."

"Surely you know every one who has a right to be on the ship?"

"Guess that's so, mister, an' who has more right than the daughter of the man who puts up the dough for the trip? Strikes me you're makin' a hash of things. But here's Mr. Vane. He'll soon put you where you belong."

Advancing from the after state-rooms came Voles. He was looking at the bridge, but the police-captain was hidden momentarily by the chart-room. He gazed at Steingall with bold curiosity. He had a foot on the companion ladder when he heard a sudden commotion on the wharf.
