Japanese Tales of Mystery & Imagination - Edogawa Rampo [33]
GIRL: Then there was the man in the blue overcoat.
MAN: Yes, with a blue felt hat, dark glasses, and a thick mustache.
GIRL : You had seen him before, hadn't you?
MAN: Yes, there I was, a striving painter boarding at your house, playing the role of a clown in the midst of your and your husbands affairs. It was one day while I was out roaming the streets that the man first attracted my attention. And when I asked the owner of the teahouse on the corner, she told me the stranger had been asking a lot of questions about your house.
GIRL: It was after you brought me this news that I happened to see him myself. The first time was outside my kitchen, and twice more near the front gate. Each time he was standing like a shadow, dressed in his baggy overcoat, both his hands shoved deep in his pockets.
MAN: I thought he was a sneak thief at first, and several servants in the neighborhood also warned me about him.
GIRL: But he turned out to be much worse, a far more dangerous character than a mere sneak thief, didn't he? Somehow, that dreadful night, his sinister form leapt to my mind the instant I gazed into my husband's tear-stained eyes.
MAN: And then you had a third hint of his plans, didn't you?
GIRL: Yes, those detective stories you started bringing us. We'd read detective stories before, of course, but you really aroused our interest in the art of crime. It all started a few months before we saw the mysterious stranger, and almost every night we used to discuss nothing but various successful crimes. Saito, my husband, of course, was the most enthusiastic of all, as you may recall.
MAN: Yes, that was about the time he thought up the best plot of them all.
GIRL : You mean that trick of dual personality. There certainly were a lot of different ways of creating a dual personality, weren't there? I remember that long list you made up.
MAN: Thirty-three different ways, if I remember correctly.
GIRL: But Saito was most impressed with the possibility of creating an utterly nonexistent character.
MAN: The theory was a simple one. For example, if a man decided to commit a murder, he would first create an imaginary character far in advance of the crime. This character would be his double. His description would be simple, with, say, a false mustache, dark glasses, and conspicuous clothing. Then he would have this double of his establish a residence far removed from his real domicile, and he would proceed to live two lives. While the real character would supposedly be away at work, the double would be at his home, and vice versa. Matters would be even more simple in the event one of the two characters went away on a long trip. With the stage thus set, the murder could be committed at an opportune time, but immediately before the crime the imaginary character would make himself very obvious to several witnesses. And then, following the crime, he would vanish completely from the face of the earth. Beforehand, of course, he would have destroyed all incriminating evidence, such as his disguise. As a result, he would be permanently missing from his home, while the real character would merely resume his former way of life. Naturally, as the crime was committed by a nonexistent character it would be a perfect crime.
GIRL: Saito kept talking about this until I thought he was going crazy. All this I recalled as I stared into his eyes. But there was one more clue to his hidden thoughts. It was that diary, which he had "hidden" for the express purpose of having me find it. But the diary was planted for me to read, so of course it didn't mention his real secrets. For example, there was not a word about his mistress.
MAN: It was like crossing out lines in a letter to make sure they'd be read.
GIRL : I read the diary from cover to cover. Several pages were devoted to the dual-personality idea. I was quite struck by his ingenious ideas. And I must say he was a wizard with the pen.
MAN : Go on.
GIRL: Well, those were the three clues I had. First, the look in his eyes; next,
