With a yawn, he turned back, fancying there was a note of relief in the policeman’s farewell. He smiled as he walked along. His conversation with Pinto had cleared up one point in his mind. The officer knew something of Mrs. Trippe’s fate. The dread he had evinced at mention of the housekeeper’s name proved that, and his prevarications and evasions were further evidence. The plea of indigestion and nervousness, coming from one of Pinto’s robust physique, was highly amusing.

Yet, illuminating as his verbal fencing match with the patrolman had been, it had merely confirmed suspicions already firmly rooted in the Phantom’s mind. As yet he had not a single iota of concrete evidence, and there were several snarled threads that had to be untangled before he could accomplish much. For instance, there was the mystery surrounding the murder of Mrs. Trippe and the equally perplexing riddle of what had become of the body. Both of them must be solved before he could go far toward attaining his object.

He stopped, noticing that his mental processes had guided his steps toward the Gage house. It was still drizzling, and he was tired and hungry and wet, but the problem on which he was engaged drove all thought of rest and food from his mind. The blackness overhead was slowly breaking into a leaden gray, and from all directions came sounds of awakening life. He walked up to the door, believing that the answers to the questions that troubled him were to be found inside the house.

Then, out of the shadows, as it seemed to him, came an undersized creature with a slouching gait and glittering cat’s eyes peering out from beneath the wide brim of a soft hat. The Phantom felt a slight touch on his elbow, and for an instant the sharply gleaming eyes scanned his face, then the queer-looking character shuffled away as swiftly and silently as he had appeared.

The Phantom was tempted to follow, but just then he noticed that a piece of paper was cramped between his fingers. He unfolded it and examined it in the meager light. All he could see at first was something crude and shapeless sketched with pencil, but gradually the blur dissolved into a symbol which he recognized.

It was a ducal coronet. The Phantom smiled as he looked down at the emblem of his old rival and enemy, the Duke. The paper handed him by the curious messenger was a reminder that the hand of his antagonist was reaching out for him, that though the Duke himself was in prison, his henchmen and agents were active, being at this very moment on the Phantom’s trail.

He put the paper into his pocket, and in the same moment the amused smile faded from his lips. For a time he had forgotten that, to all practical purposes, he was no longer the Gray Phantom, but one Thomas Granger, journalist. His lips tightened as again he gazed at the tracings on the paper. Did it mean that the Duke’s emissaries had seen through his disguise and alias, or did it mean—his figure stiffened as the latter question flashed in his mind—that Thomas Granger was a member of the Duke’s band?

In vain he pondered the problem, unable to decide whether the paper had been intended for himself or for Granger. If for himself, it seemed a somewhat idle and meaningless gesture on the Duke’s part, for his old enemy surely could gain nothing by sending cryptic messages to him. On the other hand, assuming that the reporter was the intended recipient, what hidden meaning was Granger supposed to read into a ducal coronet?

He tried to dismiss the problem from his mind until he could have a talk with Granger, but thoughts of the mysterious message and the strange messenger pursued him as he once more turned to the door. The entrance to the store was padlocked, but the lock on the side door yielded readily to manipulation with one of the tools in his metal case. A quick glance to left and right assured him he was unobserved. Closing the door and taking out his electric flash, which he had transferred among other things to the suit he was now wearing, he ran up the steep and creaking stairs.

He stood in a long and narrow hall. At one end was a stairway, presumably leading to the store below, and along the sides of the corridor were three doors. Opening one of them, he played the electric beam over the interior, for he did not think it safe to turn on the light. It was a small, tidily furnished bedroom, and the prevalence of feminine touches hinted that it had been occupied by the housekeeper. In the neatness and immaculateness of things there was not the slightest suggestion of tragedy, and he looked in vain for a sign that the occupant had been snatched from a humdrum life to a horrible death.
