I’m standing in the kitchen making coffee when I notice that the sugar container is open. This would not ordinarily qualify as an event, but the lid isn’t missing or sitting somewhere that suggests negligence. It is placed neatly beside the container, almost exactly where a person would put it if they intended to use the sugar and then became distracted before replacing it. There is also a spoon on the counter. The spoon is clean except for three visible grains of sugar near the handle, which tells me very little except that somebody has recently interacted with sugar in a way that lacked procedural closure. John Mercer drinks his coffee without sugar. I usually use one spoonful, but I haven’t touched the container yet this morning. Pandora uses sugar occasionally, depending on what she’s drinking. Mr Whiskers lacks both the necessary interest and opposable thumbs. That leaves Pandora as the most plausible participant, except she told me yesterday morning that she wouldn’t be home until after six. I remember this because I was planning dinner around it. According to the established timeline, the sugar container should not be open.
Pandora walks into the kitchen while I’m still looking at it and immediately asks, “What?” I tell her I haven’t said anything. “You’re staring at the sugar.” I ask whether she used it this morning. She says no. I ask whether she used it last night. She thinks for a moment and says she doesn’t remember. That is not especially useful. I point out that the lid was definitely closed when I left the house yesterday afternoon because I made coffee immediately before going out to run errands. Pandora pours herself a cup and says, “Then somebody opened it after you left.” I wait for her to continue. She doesn’t. “That doesn’t bother you?” I ask. She takes a drink. “No.” I explain that there were only two known people with routine access to the kitchen during that period: Pandora and John. “And a cat,” she says. I remind her that Mr Whiskers cannot open a sugar container. She looks toward the living room. “I wouldn’t say that too loudly. He likes a challenge.”
John comes into the kitchen a few minutes later, and I ask whether he used the sugar yesterday. He says no. I ask whether he remembers seeing the container open. He says no. I ask what time he got home. John stops halfway to the refrigerator and looks at Pandora. “Why am I being interviewed about sugar?” I tell him he isn’t being interviewed; I’m establishing a sequence of events. He says he got home sometime around five-thirty and went directly to his room. I ask whether Pandora was home. “I don’t know.” I ask whether he heard anything. “Probably.” I ask what. “Hal, I live here. I hear things all the time.” I point out that this is exactly why eyewitness testimony requires specific questioning. Pandora tells me to leave John alone. John takes a bottle of water from the refrigerator and retreats toward his room, but before leaving he says, “For what it’s worth, I thought I smelled coffee when I came in.” I look at Pandora. Pandora looks at John. John realizes what he has done. “Actually, forget I said that.”
Now we have coffee. That changes the situation because the sugar container alone could have been opened for any number of reasons, but sugar combined with the smell of coffee narrows the likely activity considerably. I check the coffee maker. The carafe is clean because I washed it after dinner, but there is a faint dried mark near the warming plate. Again, not proof, but consistent with use. Pandora leans against the counter watching me. “What exactly do you think happened?” she asks. I tell her I’m not prepared to speculate. “You’ve been speculating for twenty minutes.” I explain that I’m establishing whether she came home earlier than she said she did. Pandora raises an eyebrow. “Why would I hide coming home early?” I tell her I don’t know, which is precisely why assigning motive before establishing the underlying event would be irresponsible. She says, “Thank God we’re being responsible about the sugar investigation.”
At work, I make the mistake of mentioning the matter to Karen. I tell her I have evidence suggesting someone may have entered my kitchen during a period when I believed the house was empty. Karen asks whether anything was stolen. I say no. Dave asks whether anything was damaged. Again, no. Karen asks what the evidence is. I explain the open sugar container, the spoon, John’s recollection of coffee, and the mark near the coffee maker. Dave listens carefully and asks, “Do other people live with you?” I tell him that is not the point. Karen asks whether Pandora came home early. I say that is currently the leading hypothesis. “Did you ask her?” I explain that I did, but she never actually answered the question. Dave says, “Maybe because she wanted to watch you investigate a sugar bowl.” Karen laughs. I make a mental note that neither of them is taking the evidentiary significance of the spoon seriously.
When I get home that afternoon, Mrs Jenkins is checking her mail across the hall. I say hello and then, without giving her any background that might contaminate her recollection, ask whether she happened to notice anything unusual in the hallway yesterday afternoon. She thinks for a moment and says, “Pandora came home early.” I stop. There are few experiences more satisfying than receiving independent confirmation of a hypothesis before you have disclosed the hypothesis. I ask what time. Mrs Jenkins says sometime around three-thirty because she was leaving to run an errand and nearly bumped into Pandora outside our door. “She was only here for a few minutes,” Mrs Jenkins says. “Then she left again.” I ask whether Pandora was carrying anything. Mrs Jenkins thinks again. “Her purse?” This is less useful. I ask whether she smelled coffee. Mrs Jenkins looks at me. “Hal, I was going to the store, not conducting surveillance.” I thank her for her cooperation anyway.
Pandora is sitting on the couch when I walk inside. I put my keys down and tell her Mrs Jenkins saw her come home around three-thirty yesterday. Pandora smiles immediately, which is not the reaction I expected from someone whose movements have just been independently verified. “I was wondering how long it would take you to ask her,” she says. I ask why she didn’t simply tell me she came home early. She explains that she did come home early because the meeting she had scheduled ended much sooner than expected. She stopped at the house for about ten minutes before going back out to finish an errand. While she was here, she made herself a cup of coffee. She opened the sugar, heard her phone ringing in the living room, answered it, realized she was running late, poured the coffee into a travel mug, and left. The lid stayed on the counter because she forgot to put it back. The spoon stayed there for the same reason. The mark beside the coffee maker came from the travel mug. “That’s it?” I ask. Pandora says, “That’s it.”
I’m relieved, obviously, but there is also the matter of accuracy. I point out that my original hypothesis was correct: Pandora came home early yesterday. Pandora says I could have learned this in approximately six seconds by asking, “Did you come home early yesterday?” I remind her that I did ask whether she used the sugar, and she said she didn’t remember. “I didn’t remember using the sugar,” she says. “I remembered coming home.” I ask why she didn’t volunteer that information. Pandora smiles. “Because you were standing in the kitchen staring at a spoon like it had confessed to something, and I wanted to see where this went.” I stare at her. She takes a drink of coffee. “You involved Karen, didn’t you?” I don’t answer. “And Dave?” I still don’t answer. Pandora starts laughing. I tell her withholding relevant information from an active inquiry compromises the integrity of the process. She says there should never have been a process.
That evening I put the lid back on the sugar container and consider the matter resolved. Pandora came home early, made coffee, became distracted, and left again. John smelled the coffee when he returned. Mrs Jenkins happened to see Pandora in the hallway. Every piece of evidence has a mundane explanation, and more importantly, my initial observation was correct. I mention this to Pandora while she is reading on the couch. She says, “Yes, Hal. You successfully determined that I came home to the house where I live.” I tell her she is deliberately minimizing the accomplishment. Mr Whiskers jumps onto the coffee table before she can respond, walks over to my mug, and sniffs it. I move the mug away from him. He looks toward the kitchen, jumps down, and disappears around the corner. A few seconds later I hear something hit the counter, followed by a small plastic clatter. Pandora looks up from her book. I walk into the kitchen and find Mr Whiskers sitting on the counter beside the sugar container. The lid is on the floor. I look at him. He looks at me. Then I look back toward Pandora. “I would like to formally revise one assumption from this morning.” From the living room, she says, “No.” I haven’t even told her which assumption yet. That bothers me almost as much as the cat.
