of unsavory characters, men who, for a dollar and a dram of whiskey, would sell their own mothers—willing mercenaries in service to the natural science of aberrant biology.
But this was not the sort who stood shivering in the alleyway. Though bedraggled from a journey of many miles, he wore an expensive fur-lined coat that hung open to reveal a tailored suit. A diamond ring glittered on the little finger of his left hand. More striking than his regalia was his manner; the poor fellow seemed nearly mad with panic. He abandoned his cargo on the back stoop, pushed his way into the room, seized the doctor by his lapels, and demanded to know if this was number 425 Harrington Lane and if he—the doctor—was Pellinore Warthrop.
“I am Dr. Warthrop,” said my master.
“Oh, thank God! Thank God!” the tormented man cried in a hoarse voice. “Now I’ve done it. It’s right out there. Take it, take it. I’ve brought you the blasted thing. Now give it to me! He said you would—he said you had it. Quickly, before it’s too late!”
“My good man,” replied the doctor calmly. “I would gladly pay the charge, if the price is reasonable.” Though he was a man of substantial means, the monstrumologist’s parsimony soared to near operatic heights.
“The price? The price!” The man laughed hysterically. “It isn’t you who’ll pay, Warthrop! He said you had it. He promised you would give it to me if I brought it. Now keep his promise!”
“Whose promise?”
Our uninvited guest let loose a banshee howl and doubled over, clutching his chest. His eyes rolled back into his head. The doctor caught him before he hit the floor, and eased him into a chair.
“Damn him to hell—too late!” the man whimpered. “I am too late!” He wrung his hands in supplication. “Am I too late, Dr. Warthrop?”
“I cannot answer that question,” replied the doctor. “For I have no idea what you’re talking about.”
“He told me you would give me the antidote if I brought it, but I was delayed in New York. I missed the train and had to wait for the next one—more than two hours I had to wait. Oh, God! To come all this way only to die at the end of it!”
“The antidote? The antidote to what?”
“To the poison! ‘Bring my little gift to Warthrop in America if you wish to live,’ he told me, the devil, the fiend! So I have, and so you must . Ah, but it is hopeless. I feel it now—my heart—my heart—”
The doctor shook his head sharply and with a snap of his fingers directed me to fetch his instrument case.
“I will do all within my power,” I heard him say to the poor man as I scampered off. “But you must get a grip on yourself and tell me simply and plainly…”
Our tormented courier had fallen into a swoon by the time I returned, eyes rolling in his head, hands twitching in his lap. His face had drained of all color. The doctor removed the stethoscope from the case and listened to the man’s heart, bending low over the quivering form, his legs spread wide for balance.
“Galloping like a runaway horse, Will Henry,” the monstrumologist murmured. “But no abnormalities or irregularities that I can detect. Quickly, a glass of water.”
I expected him to offer the distressed man a drink; instead Warthrop dumped the entire contents of the glass over his head. The man’s eyes snapped open. The mouth formed a startled O .
“What sort of poison did he give you?” demanded my master in a stern voice. “Did he say? Answer!”
“Tip… tipota… from the pyrite tree.”
“Tipota?” The doctor frowned. “From what kind of tree?”
“Pyrite! Tipota, from the pyrite tree of the Isle of Demons!”
“The Isle of Demons! But that is… extraordinary. Are you quite certain?”
“Bloody hell. I think I would remember what he poisoned me with!” the man sputtered vehemently. “And he said you had the antidote! Oh! Oh! This is it!” His hands clawed at his chest. “My heart is exploding!”
“I
