Ingrid Sjostrom’s bag
The Shape of WaterIngrid Sjostrom’s bag is both a personal possession and a manufactured piece of evidence: Pietro Rizzo uses it to suggest that Ingrid was connected to Silvio Luparello’s death, while Salvo Montalbano ultimately destroys its usefulness by throwing it into the sea. Its significance lies not in any described contents or distinctive appearance, but in where it is found, the discrepancy it can exploit, and the story Rizzo intends it to tell. The bag makes an uncertain movement through the plot carry the weight of an accusation.
Identity and Function
The bag belongs to Ingrid Sjostrom and bears her initials, a feature that makes it readily identifiable as hers. Rizzo finds it in the little house and decides to use it. The narrative does not describe its design or give an inventory of what it contains; its evidentiary force comes instead from its ownership and its placement within a chain of events that Rizzo can manipulate.
That distinction matters. The bag is not simply a possession accidentally left behind: in Rizzo’s scheme it becomes a physical prop that can be presented as proof. Its apparent directness—Ingrid’s initials on an object found in a location associated with the case—conceals the deliberate choices behind its presence there. The bag seems to make a connection visible, but that connection has been arranged.
How Rizzo Makes It Evidence
Rizzo’s plan depends on two separate objects: the necklace and the bag. He intends the necklace to serve as the visible first piece of evidence, while keeping the bag as a reserve. If the necklace is found, it can be used to argue that Ingrid was at the Pasture when Luparello died. If someone pockets the necklace and keeps quiet about finding it, Rizzo can still produce the bag. The two objects give him alternative ways to support the same accusation.
The bag’s role draws force from a discrepancy between two accounts. Salvo Montalbano observes that a woman leaving Luparello’s car was holding a bag, but that she no longer had it when a car picked her up along the provincial road. He uses that inconsistency to find the bag. Rizzo, for his part, has placed it where it can be made to support his version of Ingrid’s movements. The object therefore links two kinds of evidence: what witnesses say they saw and what can later be displayed as material confirmation.
The bag’s initials strengthen the appearance of certainty without establishing the accusation Rizzo wants to make. They identify its owner, but they do not by themselves explain how it came to be at the little house or prove that Ingrid was involved in Luparello’s death. Rizzo’s strategy depends on letting the object’s recognizable ownership stand in for a proven account of its journey.
Recovery and Destruction
After tracing the discrepancy, Montalbano obtains the bag and carries it back to the house at Capo Massaria. He finds the house empty, takes Ingrid’s belongings from the wardrobe, and leaves with the bag. At the picture window, the sea below the headland offers a way to prevent it from being found again. Montalbano weights the bag with silverware and a heavy crystal ashtray, swings it around, and hurls it into the water.
Ingrid arrives with her headlights on and asks where the bag is. Montalbano tells her he has thrown it into the sea and that there is nothing left with which to frame her. She gets out, embraces him for a while with her head against his chest, then returns to her car and drives away without looking back. The bag’s removal is thus also an immediate intervention in Ingrid’s danger: Montalbano does not merely identify the trap but eliminates the object on which Rizzo could rely.
Narrative Significance
The bag shows how an ordinary object can acquire a political and criminal function through placement and interpretation. Rizzo’s scheme turns ownership into a suggested presence, and a suggested presence into a route toward blame. Against that manufactured certainty, Montalbano reads the gaps between testimony and refuses to let the object complete the accusation. The bag’s movement—from the little house, into Montalbano’s hands, and then out over the sea—marks the contest between Rizzo’s effort to make evidence speak for him and Montalbano’s decision to silence it.
Its destruction has a double edge. It protects Ingrid from a piece of evidence designed to implicate her, but it also removes the object rather than putting it forward as proof of Rizzo’s plot. The bag therefore embodies the practical and moral pressure of the case: safeguarding someone from a false charge means intervening in the material record. Once it disappears beneath the water, Rizzo loses a reserve card, while Ingrid’s immediate response registers the personal consequence of Montalbano’s choice.
