A Modern Wizard
Rodrigues Ottolengui (1861–1937)
A brilliant, cold-blooded physician commands the forces of human will and chemical science, only to discover that the most dangerous experiments are those performed upon oneself.
In Short
This late-nineteenth-century mystery blends the tropes of the classic courtroom thriller with the burgeoning science-fiction fascination with hypnotism and the "germ theory" of human behavior. It follows a charismatic doctor, Emanuel Medjora, who exerts an almost supernatural influence over those around him, leading to accusations of murder and a harrowing descent into madness. By grounding its suspense in the intellectual debates of the 1890s—specifically the power of suggestion and the morality of the legal system—the story provides a unique window into a period obsessed with the limits of the human mind.
The Story
The narrative begins in the spring of 1873, in the law offices of Dudley and Bliss. Two young partners, eager for their first major criminal case, find themselves entangled in the defense of Dr. Emanuel Medjora, a man accused of murdering a young woman named Mabel Sloane via morphine poisoning. The ensuing trial is a high-stakes display of legal maneuvering, where the prosecution attempts to prove the doctor’s guilt, while the defense argues that the death was a suicide. The doctor remains an enigmatic, almost hypnotic figure throughout, successfully evading conviction through a combination of expert testimony and his own calm, manipulative demeanor.
Following his acquittal, the second half of the book shifts from the courtroom to the more insular, atmospheric setting of the doctor’s private life. We are introduced to Leon Grath, a young man whom the doctor has taken under his wing, and Agnes Dudley, the daughter of the now-prominent judge. The doctor is revealed to be a man of immense, if unsettling, secrets, claiming a lineage of ancient Mexican priesthood and possessing a dangerous, obsessive interest in "Sanatoxine"—a mysterious substance he believes can unlock the full potential of the human mind.
As the story progresses, the doctor’s influence over Leon grows, and he attempts to subject the youth to hypnotic experiments. Leon, however, proves resistant, and the doctor’s own mental state begins to deteriorate under the weight of his hubris. When Madame Medjora, the doctor’s wife, dies suddenly of diphtheria, the detective Jack Barnes—who has been tracking the doctor since the earlier trial—is convinced of foul play. He initiates a final confrontation. The climax is a chilling revelation: the doctor’s scientific quest has been a path to destruction. Medjora, believing his "Sanatoxine" experiment has granted him god-like power, loses his grip on reality entirely, collapsing into a manic, shrieking state of insanity. He is revealed to be not a "wizard" of science, but a man broken by his own unchecked desire for control, ultimately proving that his intellectual pursuit was a self-inflicted poison.
How It Unfolds
The firm finds its footing Two young lawyers, Dudley and Bliss, open their practice in New York, hungry for a high-profile case that will launch their careers. They soon find their opportunity when Dr. Medjora is indicted for the poisoning death of Mabel Sloane.
The battle in the courtroom The trial unfolds as a meticulous clash between the prosecutor’s pursuit of justice and the defense’s clever use of legal technicalities. Dr. Medjora manages to manipulate the narrative, turning the tide in his favor by casting doubt on the nature of the poison and the patient's own mental state.
The influence of the physician After his acquittal, Medjora retreats into a private sphere, where he exerts a profound psychological pull on his ward, Leon. He introduces the young man to his radical theories on the "germ theory of crime" and the hidden potential of the human will.
The detective’s suspicion Jack Barnes, a persistent investigator, continues to shadow the doctor, certain that his involvement in deaths is no coincidence. He watches as the household is shaken by the sudden illness of the doctor’s wife, Madame Medjora.
The final collapse Barnes confronts the doctor in his home, leading to a frantic scene where Medjora, high on his own chemical concoctions, attempts to exert his will. The doctor breaks down, his sanity shattered, revealing the hollow, tragic core of the "wizard" who thought he could master life and death.
The People
Dr. Emanuel Medjora is the titular "wizard," a man of immense intellect and cold, magnetic charisma. He seeks absolute control over his environment and the minds of others, viewing himself as superior to the common morality of the law. He ends his journey in complete cognitive ruin, reduced to a manic state by his own dangerous experiments.
Leon Grath is a sensitive, intellectually curious youth who initially idolizes the doctor. He serves as the primary subject for Medjora's psychological tests, though his own innate moral compass eventually helps him resist the doctor's manipulation. He escapes the doctor's influence just as the older man descends into madness.
Jack Barnes acts as the narrative’s moral anchor and the embodiment of society’s protective instinct. As a detective, he is defined by his relentless focus; he is the only one who refuses to be charmed by Medjora. Through his persistence, he exposes the doctor's crimes and forces the final, inevitable confrontation.
Mortimer Dudley and Robert Bliss represent the legal machinery of the era. Ambitious and sharp, they grow from struggling novices into prestigious members of the judiciary and the District Attorney’s office, illustrating the professional stability that contrasts sharply with the doctor’s chaotic, self-destructive path.
In Its Own Voice
Describing the doctor’s chilling ability to dominate others, the author writes:
"He was mesmerized, why might he not be hypnotized? Still, the Doctor was loath to take a risk."
Regarding the nature of his "wizardry" and the dangerous power he claims to possess, the doctor declares:
"I am the Wizard! I do what I please! You did not think that I could break it! Ha! Ha! Ha! You do not know Emanuel Medjora!"
Reflecting on the deeper, darker themes of the story, the author notes the ease with which one might lose one's way:
"However little we suspect it, there is an unseen but potent energy which urges us forward towards--the grave, and--whatever follows death."
What It's Really About
At its core, the book explores the tension between scientific ambition and human morality. It questions whether the mind is truly sovereign or merely a slave to suggestion and external influence. By framing crime as a "contagion"—a germ that spreads through society—it challenges the judicial system’s focus on punishment, arguing instead for reform and the clinical treatment of the "vicious." The book is essentially an inquiry into the "wizardry" of the human will: how far can a person manipulate their own nature and the lives of others before the internal structure of their own sanity collapses? It asks if the search for ultimate knowledge is a path to enlightenment or a descent into a narcissistic, destructive void.
Why Read It Today
Readers who enjoy the slow-burn atmospheric mysteries of the Victorian era will find much to admire here. It reads like a precursor to the psychological thriller, grounding its suspense in the intellectual anxieties of the 1890s—a time when mesmerism and early neurology were capturing the public imagination. The prose is precise and dignified, capturing the formal, slightly stiff manners of the time while maintaining a genuine sense of dread.
It is important to note, however, that the book reflects the attitudes of its day. The dialogue can be melodramatic, and the "theories" regarding race and ancient history are products of a period long before modern archaeology or psychology. Readers should also be prepared for a narrative that moves at a measured, deliberate pace, often pausing for long debates on law and philosophy. Yet, for those interested in the history of the genre, the book remains a fascinating relic. What sticks with you is not just the mystery of the murders, but the portrait of a man so obsessed with his own power that he becomes the architect of his own destruction. It is an honest, sometimes jarring, look at the dangerous intersection of intellect and ego, making it a compelling read for those who appreciate the darker side of human ambition.
