of nicotine. By the way, I have a sample. We can take care of him on that charge, without a shadow of doubt."
Winter blew softly on the back of his friend's head.
"You're thorough, Charles, thorough!" he murmured. "It's a treat to work with you when you get really busy."
Furneaux ran his thumb across the end of several leaves.
"I can tell you now," he said, "that there's nothing of real value in the earlier notes. So far as I can judge, they refer either to a sort of settlement with his wife or chance phrases used by Doris Martin which might imply that she was heart whole and fancy free. There's not a bally word dealing with the murder, or that can be twisted into the vaguest allusion to it. But here's a plan and section which have a sort of significance. I've seen the place, so recognized it, or thought I did. We must check it, of course. Here you are! You know the footbridge across the river from Bush Walk?"
"Yes."
"The eastern end is supported on a hollow pier of masonry, in which one might tog up unseen. These drawings would be useful as an Aide Memoire on a dark night. A false step, with the river in flood, might be awkward."
"What's that on the opposite page?"
"I give it up—at present."
This somewhat rare display of modesty on Furneaux's part was readily understandable. A series of straight lines and angles conveyed very little hint of their purport; but Winter smiled behind his friend's back.
"I've been prowling about this wretched inn longer than you," he said. "Look outside, to the left."
"Don't need to, now," cackled Furneaux. "It's the profile of a wall, gate, and outhouse along which one could reach the window of the club-room. Would you mind stopping grinning like a Cheshire cat?"
"Anything else?"
"Yes. This one:
'S. M.? 1820.'
That beats you, eh?"
"Dished completely."
"Doris Martin, as usual, supplies the answer. An old volume of the Sussex Miscellany, probably that for 1820, contains the full story of Owd Ben. I might have mentioned it to you, but focussed on current events. Siddle has it among his books, which, by the way, are made up largely of scientific and popular criminal records."
"Is that the lot?"
"I'm afraid so. Have a look."
"Just a minute. I want to think."
Winter turned and gazed through the open window. Seldom had a more gracious June decked England with garlands. The hour was then high noon, and a pastoral landscape was drowned in sunshine. The Chief Inspector cut the end off a cigar dreamily but with care.
"Broadmoor—perhaps," he muttered. "But we can't hang him yet, Charles. A couple of knots and a theory won't do for the Assizes. We haven't a solitary witness. Hardly a night but he goes home at 9.30. If only he had killed Grant! But—Adelaide Melhuish!"
In sheer despair he struck a match.
"Well, let's overhaul these duds," said Furneaux savagely. "I'll chance the dinner hour for the return visit. Steynholme folk eat at half past twelve to the tick, and you can hardly get up another horse show."
There was a knock at the door.
"Let me in, quick!" came Peters's voice, and the handle was tried forcibly.
"Go away! I'm busy!" cried Winter.
"This is urgent, devilish urgent," said Peters.
Furneaux snatched up the note-book, and Winter tore off his coat, throwing it over the package which reposed in an armchair. Then the Chief Inspector unlocked the door, blocking the way aggressively.
"Now, I must say—" he began.
But Peters clutched his shoulder with a nervous hand.
"Siddle has just hurried up the street and entered his shop," he hissed.
The journalist had not only kept his eyes open, but excelled in the art of putting two and two together, an arithmetical calculation which, as applied to the affairs of life, is not so readily arrived at as many people imagine.
"Buncoed! He's missed his keys!" shrilled Furneaux.
"Confound the man! He might at least have attended his mother's funeral!" stormed Winter, retrieving his coat.
Thus it happened that Furneaux was the first down the stairs, though the three emerged from the door of the inn on each other's heels. A stout man, in all likelihood a farmer with horses for sale, was mounting the two steps which led to the entrance. His head was down, and his weight forward, so he successfully resisted Furneaux's impact, but Peters and Winter were irresistible, and he tumbled over with a muffled yell.
At that instant Siddle quitted his shop, and headed straight for the post office. In his right hand he carried an automatic pistol. The street was wide. Furneaux, absolutely fearless in the performance of his duty, ran in a curve so as to bar the chemist's path, and it was then that Siddle saw him. The man's face was terrible to behold. His eyes were rolling, his teeth gnashing; he had bitten his tongue and cheeks, and his stertorous breathing ejected from his mouth foam tinged with blood.
"Ha!" he screamed in a falsetto of fury, "not yet, little man, not yet!"
With that he raised the pistol, and fired point-blank at the detective. Furneaux ducked, and seized a small stone, being otherwise quite unarmed. He threw it with unerring aim, and, as was determined subsequently, struck the hand holding the weapon. Possibly, almost by a miracle, the blow caused a faulty pressure, because the action jammed, though the pistol itself was most accurate and deadly in its properties.
By this time Winter, sweeping Peters aside, was within ten feet of the maniac, who turned and ran into the shop. The door, a solid one, fitted with a spring lock, slammed in the Chief Inspector's face, and resisted a mighty effort to burst it open. A few yards away stood an empty, two-wheeled cart, uptilted, and Winter demanded the help of a few men who had gathered on seeing or hearing the hubbub.
"I call on you in the King's name!" he shouted. "We must force that door! Then stand clear, all of you!"
He raced to the cart, and, when his object was perceived, willing hands assisted in converting the heavy vehicle into a battering-ram. The gradient of the hill favored the attack, which was made at an acute angle, and the first assault smashed the lock. There were a couple of seconds' delay while the cart was backed out, and the detectives rushed in, Furneaux leading, because Winter gave his great physical strength to the shafts. But the Chief Inspector grabbed his tiny friend by the collar as the latter darted around the counter and into the dispensary in the rear.
"Two of us can't go abreast, and you'll only get hurt," he said, speaking with a calmness that was majestic in the circumstances.
"The nicotine is gone!" yelped Furneaux; both saw that the safe stood open.
Behind the dispensary was a small passage, whence the stairs mounted, and a door led to the kitchen. That door was closed now, though it was open when Furneaux ransacked the house. Therefore, they made that way at once. No ordinary lock could resist Winter's shoulder, and he soon mastered this barrier. But the kitchen was empty—the outer door locked but unbolted. Since it is practically impossible for the strongest man to pull a door open, the two made for the window, and tore at screws and catch with eager fingers. Furneaux, light and nimble-footed, scrambled through first, so it was he who found Siddle lying in the orchard beyond the wall of the yard. The unhappy wretch had swallowed nearly the whole remaining contents of the bottle of nicotine, or enough to poison a score of robust men. He presented a lamentable and distressing spectacle. Some of the more venturesome passers-by, who had crowded after the detectives and Peters, could not bear to look on, and slunk away in horror.
Furneaux soon brought an emetic, which failed to act. Siddle breathed his last while the glass was at his lips.
In that moment of crisis
