A Summer Day's Entry
Doctor Glas begins his diary entries on a warm July day in Stockholm, thinking about his lonely life as a doctor and his sadness. He describes his routine, his lack of close human connection, and his feeling of isolation even when surrounded by people. He expresses a general tiredness with life and a philosophical distance, often thinking about existence, happiness, and suffering. He hints at a past sorrow involving a woman named Helga, though details are few, which sets the somber, reflective tone for the story and reveals Glas's inner world.
The Minister and His Wife
Helga Gregorius, the young wife of Pastor Gregorius, visits Doctor Glas's office, complaining of tiredness and unease. During her check-up, she tells Glas about her strong dislike for her husband's physical advances. She describes Pastor Gregorius as an old, repulsive man whose touch sickens her, and she feels trapped in their marriage. Glas, who already dislikes the minister because of his public image and perceived hypocrisy, feels immediate sympathy and a growing desire to protect Helga. This meeting starts his dangerous obsession and his wish to help her.
A Moral Dilemma
After Helga's confession, Doctor Glas becomes consumed by her situation. He starts imagining ways to free her from her oppressive marriage, at first considering non-violent solutions like convincing Pastor Gregorius to stop having sex. He visits the minister, pretending to discuss public health, and subtly probes Gregorius's character and his views on marriage and duty. Glas finds the minister's self-righteousness and insensitivity disgusting, which strengthens his belief that Helga is suffering unfairly. His inner thoughts show a conflict between his medical ethics and his growing desire to act for Helga, even if it means breaking moral rules.
The First Deception
Doctor Glas plans a way to give Helga temporary relief from her husband. He falsely tells Pastor Gregorius that Helga has a serious heart condition that makes sexual activity dangerous and possibly fatal. Gregorius, though at first doubtful and resistant, eventually agrees to Glas's medical advice, though unwillingly. This manipulation gives Helga a period of relief, and she thanks Glas, which deepens his emotional involvement in her well-being. Glas feels a twisted satisfaction in his deception, seeing it as a necessary wrong to ease Helga's suffering and proof of his growing power over the situation.
Helga's Affair
During the time of forced abstinence, Doctor Glas notices Helga's renewed energy and happiness. He sees her often in the city, frequently with a handsome young student named Reverend Recke. Glas's initial pleasure at Helga's improved state soon turns into a mix of jealousy and a feeling of betrayal when he realizes they are lovers. He feels a pang of disappointment, as if his efforts for her were not entirely for her freedom, but perhaps for some unspoken, unacknowledged desire of his own. This discovery complicates his moral view, as his protective instincts now clash with his own unrequited feelings and the knowledge of her infidelity.
The Minister's Persistence
Pastor Gregorius, growing impatient and suspicious of his wife's long 'illness,' confronts Doctor Glas. He says he doesn't believe in Helga's heart condition and demands that Glas take back his diagnosis, insisting on his right to his wife. Gregorius's self-centeredness and lack of empathy further fuel Glas's contempt. The minister's persistence and his refusal to consider Helga's feelings confirm Glas's belief that Gregorius prevents Helga's happiness and freedom, and that his continued existence causes her deep suffering. This confrontation pushes Glas closer to thinking about more extreme actions.
The Idea of Murder
Faced with Gregorius's firm demands and Helga's renewed despair, Doctor Glas increasingly considers murder as the only lasting solution. He comes up with detailed ethical and philosophical reasons for such an act, arguing that some lives are not worth living and that removing a source of suffering can be a moral must. He reasons that Gregorius's death would free Helga and, more broadly, serve humanity by getting rid of an offensive person. He carefully plans how he might commit the murder without being caught, weighing different methods and their outcomes, which shows how deep his obsession is.
The Poisoning
Doctor Glas carries out his plan. He invites Pastor Gregorius to his office, supposedly to discuss a new treatment for his 'heart condition.' During the consultation, Glas offers Gregorius a glass of water containing a lethal dose of cyanide. Gregorius, unsuspecting, drinks it. Glas watches the minister's final moments with a chilling detachment, recording the physical effects of the poison in his diary. He feels a strange mix of triumph and emptiness, having executed his plan with clinical precision. The act is presented as both a liberation for Helga and a dark, definite expression of Glas's own will.
Aftermath and Reflection
In the days after Pastor Gregorius's death, which is officially attributed to a heart attack, Doctor Glas appears composed. Inside, however, he deals with the aftermath of his actions. He observes Helga's reaction, noting her relief but also some sadness and perhaps guilt. He feels no regret for the act itself, believing it was justified, but he is left with a deep sense of isolation and a realization that his deed has not brought him the peace or connection he might have subconsciously wanted. His diary entries become even more introspective, exploring responsibility, justice, and the ultimate pointlessness of human effort.
The Burden of Secrecy
Life continues for Doctor Glas, but he carries the heavy burden of his secret. He continues his medical practice, interacts with society, but remains alone. He occasionally sees Helga, who eventually moves on with her life, perhaps marrying Reverend Recke. Glas realizes that his grand act of 'liberation' has not brought him closer to Helga or to any personal fulfillment. The novel ends with Glas continuing his diary entries, reflecting on the mystery of human existence, good and evil, and his own place in a world where he has committed a serious wrong, yet remains outwardly untouched by justice, only by his own inner solitude.
