He did not realise the damage done to his car, or listen to a word that passed between Thrush and his chauffeur; he had eyes only for those of his child who had been lost but was found, and not a thought in his head outside the story he extracted piecemeal on the spot. Poor Pocket told it very volubly and ill; he would not confine himself to simple facts. He stated his suspicion of Baumgartner’s complicity in the Hyde Park affair as though he knew it for a fact; cited the murders in Holland Walk and Park Lane as obvious pieces of the same handiwork, and yet declared his conviction that the actual hand was not Dr. Baumgartner’s at all.
“But why should you think he had an accomplice, Tony?”
“He was unarmed the other morning. I’m quite positive of that. And his niece, who lives with him, has never seen a firearm of any kind in the house.”
“Well, he’s villain enough to hang, if ever there was one! It’s time we laid hold of him. Where’s Mr. Thrush? I thought you’d taken him on in the car?”
This to the chauffeur, now the centre of the carrion crowd that gathers about the body of any disabled motor. The chauffeur, a countryman like his master, was enjoying himself vastly with a surreptitious cigarette and sardonic mutterings on the cause of his scattered spokes; the facts being that he had nearly fallen asleep at his wheel, which Mr. Upton had incontinently taken into his own less experienced hands.
“The car won’t take anybody anywhere to-day,” explained the chauffeur, with his cigarette behind his back. “I shall have to get a lorry to take the car.” He held his head on one side suddenly. “There’s a bit o’ tyre trouble for somebody!” he cried, grimly.
Indeed, a sharp crack had come from the direction of the river, not unlike the bursting of a heavy tyre; but Pocket Upton did not think it was that. He caught his father’s arm, and whispered in his father’s ear, and they plunged together into a side street broader than the asphalt thoroughfare, but with scarcely a break in either phalanx of drab mediocre dwellings, and not a creature stirring except themselves and a few who followed. The hog’s back of a still more deserted bridge arched itself at the foot of the street, its suspension cables showing against the sky in foreshortened curves. As they ran a peculiarly shrill whistle cut the morning air like a streak of sound.
“P’lice!” screamed one of those bringing up the rear, and they easily spurted past father and son, each already contending with his own infirmity. Mr. Upton was dangerously scarlet in the neck, and Pocket panting as he had not done for days. In sad labour they drew near the suspension bridge, to a crescendo accompaniment on the police whistle. It was evidently being blown on the Embankment to the right of the bridge, and already with considerable effect. As the pair were about to pass an intermediate turning on the right, a constable flew across it on a parallel course, and they altered theirs with one accord. Pocket panted after the constable, and his father thundered after Pocket, into a narrow street debouching upon a fenced strip of greenery, not too dense to hide broad pavement and low parapet on its further side, with a strip of brown river beyond that, and a skyline of warehouses on the Surrey shore.
The narrow garden had not been opened for the day. There was a gate opposite the end of the road, another gate leading out on the Embankment opposite that. Between the two gates a grimy statue rose upon a granite pedestal, a meditative figure clad to the heels in some nondescript garment, and gazing across the river as he sat with a number of discarded volumes under his chair. It was a peculiarly lifelike monument, which Pocket would have been just the boy to appreciate at any other time; even now it struck him for an instant, before his attention was attracted to the group of commonplace living people on the Embankment beyond the narrow garden. They were standing together on the far side of one of the fixed seats. There was the policeman who had blown the whistle, and a small but motley crew who had answered to the call. Conspicuous units were a gentleman in dressing-gown and pyjamas, a couple of chimneysweeps, and a labouring cyclist on his way to work. They had formed a circle about some hidden object on the ground; and long before the new-comers could run round and join them, the schoolboy had steeled himself to look upon another murdered man. He was in no hurry to look; apart from a natural dread of death, which he had seen for the first time, and then unwittingly, only the other morning, it was the murderer and not his victim of whom the boy was thinking as he arrived last upon the scene. It was Dr. Baumgartner whom he half expected to see swimming the river or hiding among the bushes in the enclosed garden; for he was not one of the group on the Embankment; and how else could he have made his escape? The point was being discussed as Pocket came into earshot; all he could see of the fallen man was the soles of his boots upright among living legs.
“Is he dead?” he asked of one of the chimneysweeps, who was detaching himself from the group with the air of a man who had seen the best of the fun.
