The Blood Prank on Margrete Sundelin

The Blood Prank on Margrete Sundelin is an intrusion into the Sundelin family’s ordinary domestic life, staged to make a sleeping baby appear gravely harmed. Its decisive effect is not physical injury but the sudden collapse of Lily Sundelin’s confidence that she would sense any danger to her daughter: the blood is not Margrete’s, yet the family’s sense of safety does not simply return with that discovery.

Domestic Calm and a False Assurance

The incident begins on a warm summer day. Lily is preparing a chicken pie at the kitchen counter while Margrete sleeps in her pram beneath a maple tree behind the house. She is not indifferent to the baby: she believes she would immediately hear or feel even a small change, whether Margrete sneezed, coughed, hiccupped, or cried. Lily imagines their bond as a line that transmits the slightest tug, and thinks of her daughter as present in her head, blood, fingers, and heart. That confidence is intimate, but it is also mistaken. While Lily works inside, a person slips out of the dense forest, reaches the pram in a single bound, and pushes the crocheted blanket aside. Lily feels nothing.

The domestic scene sharpens the contrast between the care Lily believes she is exercising and the attacker’s knowledge of the family’s routine. She has set the table and is preparing for Karsten Sundelin to return; her attention moves between cooking, the house, and the sleeping child. She has assumed that Margrete’s sounds would reach her. The prank exploits the gap between that felt connection and the practical fact that the pram is outside and out of sight. The narrator does not establish how the blood was placed or where it came from; the later confirmation that it was not Margrete’s blood makes the scene a deliberate deception rather than an injury.

Discovery and Immediate Crisis

A foreboding comes over Lily after she has, in her own sense, shut Margrete out of her mind. She notices that the blanket is crumpled, initially trying to explain it as the movements of a baby. Then she sees the blood. When she pulls back the blanket, Margrete appears covered in it. Lily falls to the ground, unable to rise, overcome by nausea and terror, and screams. The ordinary object that should keep the child warm has become evidence of a catastrophe—or seems to be one until the truth is known.

Karsten runs around the corner, sees Lily on the ground and the nearly black, slick blood, and reaches the pram in four steps. He lifts Margrete against his chest and orders Lily to get the car. His response is immediate and practical, set against Lily’s bodily collapse. At the hospital, the parents wait in a state they later describe as pure hell. The suspense turns on what they cannot yet know: the sight of blood gives them no way to distinguish a staged scene from a mortal wound.

A nurse finally brings Margrete through the glass doors wrapped in a white blanket. She is warm and moving her hands. The nurse tells the parents that the baby is completely unharmed, then repeats the reassurance with its crucial explanation: the blood was not Margrete’s, and the police have been called. The revelation resolves the question of the child’s physical condition but confirms that someone deliberately created the appearance of injury. The prank’s success lies in the interval before that confirmation, when the parents have to experience the apparent emergency as real.

Investigation and Exposure of the Perpetrator

The police consider the act planned rather than spontaneous. Jacob Skarre reasons that the perpetrator must have surveyed the house and learned the family’s routines, including when Margrete slept and perhaps for how long. He considers the possibility that the person hid behind a tree to watch Lily’s reaction. His judgment that the act is evil reflects its calculated use of a parent’s fear, not merely the disturbance of property or a harmless joke.

Konrad Sejer agrees that the Sundelins may have unknowingly offended someone, but he also considers other possibilities, including a mentally unstable person or someone acting out of personal grievance, jealousy, or a desire to mark territory. These are investigative hypotheses, not established explanations of the motive. The scene itself supports the narrower conclusion: whoever staged it knew enough about the household’s daily pattern to approach the pram when Lily was inside and leave before she noticed.

Johnny later thinks of the baby beneath the tree and imagines Lily and Karsten keeping her constantly within sight from then on. He pictures the three of them as a tightly enclosed, happy family and recognizes that he has given them a new sense of reality: every step outside the house can now seem risky. His private satisfaction makes clear that the incident was not an accidental fright. It was meant to alter how the Sundelins experience their own home and their child’s vulnerability. Later, when Sejer investigates another prank, he describes the perpetrator as someone who typically appears to watch the deception play out, reinforcing the pattern of surveillance and observation behind the campaign.

Aftermath and Significance

In the immediate aftermath, Lily wants to go home rather than speak to anyone. She longs to retreat with Karsten and Margrete into their bedroom and stay there. She resolves never again to let the baby sleep in the pram beneath the maple tree, never to leave her unsupervised, and never again to shut her out of her mind. These vows show how the prank persists after the false emergency has ended: the attacker has not harmed Margrete, but has made vigilance feel necessary and ordinary space feel unsafe.

The incident also sets up a recurring method in Johnny’s campaign: learning when people will be vulnerable, arranging a frightening message or appearance, and anticipating the reaction. In this first case, the target is not only an infant but the parents’ confidence in their ability to protect her. Lily’s imagined bond had promised that no danger could arrive without warning; the person at the pram demonstrates that an intrusion can happen beyond her senses. The later knowledge that Margrete was unharmed does not undo the discovery, the hospital wait, or the family’s altered habits. The prank’s lasting consequence is precisely this conversion of an ordinary act of care into fear of what might happen when the child is briefly out of sight.
