The building was in a quiet uproar. People milled around and talked in hushed tones. In contrast, the grim quiet of one of the apartments police moved around with quiet efficiency. In the room was a familiar figure.
"Who is he and how did he die?" Mouri asked, as the police collected the body, evidence and items of interest from around the room. And when it came to the items of interest, the room was filled with a great number of them. A spiny cactus on a window ledge, the aquarium with the eel and more that made the room unappealing. The smell of skunk and unwashed socks added to the unwelcoming ambiance of the room.
Out of habit, because of how often Mouri ended up at a crime scene for one reason or another, Megure told him. "Gurin Chi. Forty-two years old. Bachelor. Owns a dog. Really disliked by everyone who knew him. We have him on record for cruelty to the dog. One of the kids who lives on this floor said that he 'was a monster and had bugs in his teeth when he smiled and that his older brother said they were termites'."
Megure closed his notebook, "As to the cause of death, we'll have to wait for the results from the autopsy. We think it was something he ate." He pointed to a couple of pieces of evidence that were being bagged and photographed, "It might be that banana with the greasy black peel or the tomato with moldy purple spots."
He nodded toward the sandwich that seemed to aspire for a horror movie with the ingredients inside, "And that is, we think, a three decker sauerkraut and toadstool sandwich. The sauce on it reacts positively for arsenic."
Mouri shook his head. "And, judging by the bites, he sampled some of all of that food. A sandwich with arsenic sauce! That's one condiment I'll pass on!"
