Socks, every Monday: 「毎週 月曜日 です。」 A hair clip has gone missing too.
Who is Suzuki Ken'ichi?
Show answer
Shizuko's next-door neighbour, a young man who is very nervous. He says he knows nothing about the socks.
What does Shizuko find behind the washing machine?
Show answer
An old basket holding socks, clips, pins and a letter.
Who is the letter to, and what does it say?
Show answer
It is addressed to the writer's mother. Every Monday the writer has been looking for the socks her mother likes; the mother is in hospital, winter is coming, and the hospital is cold.
What does Suzuki want to do at the end of chapter 2?
Show answer
Call the police. He thinks Shizuko knows who the culprit is. She says nothing and holds the letter tight.
Grammar to notice: ます becomes ません
The whole story is told in the polite present: actions end in ます, descriptions in です. To make them negative, ます becomes ません, and です becomes では ありません (じゃ ありません in speech). A mystery about things that have gone missing is full of negatives, so you meet them in almost every paragraph.
シズ子 は 洗濯室 に 行きます。
Shizuko wa sentakushitsu ni ikimasu.
Shizuko goes to the laundry room.
The polite present, the base of every verb here.
靴下 が ありません。
kutsushita ga arimasen.
The socks aren't there.
あります → ありません. The second sentence of chapter 1.
本当 ですか。 知りません
hontō desu ka. shirimasen.
Really? I don't know anything about it.
Suzuki's reply. 知りません is the polite negative of 知る (to know), the usual way to say "I don't know".
泥棒 では ありません。
dorobō de wa arimasen.
It isn't a thief.
です → では ありません. Chapter 2.
シズ子 は 何 も 言いません。
Shizuko wa nani mo iimasen.
Shizuko says nothing.
何 も with a negative verb means "nothing". Near the end of chapter 2.
One more pattern sits in chapter 2: 字 は 小さくて、 丁寧 です (ji wa chiisakute, teinei desu), "the writing is small and careful". The い-adjective 小さい becomes 小さくて to join a second description.
Reading The Monday Mystery at A1
The setting is a 団地, a large block of rented flats with shared facilities, so a shared laundry room is an everyday place for neighbours to cross paths. That makes it a good stage for a small, domestic crime with no danger in it.
Look out for ドキドキ, the sound of a pounding heart. Japanese uses many words like this, and they are easy to remember because they sound like what they mean.
Names come family name first: 田中 シズ子 is Shizuko Tanaka and 鈴木 健一 is Ken'ichi Suzuki. The narrator calls her シズ子 and him 鈴木 さん.
Frequently asked questions
Is this story suitable for complete beginners?
If you can read hiragana and katakana, yes. The sentences are short and polite. Kanji words like 洗濯室 (laundry room) and 靴下 (socks) repeat often enough that you'll stop tapping them by chapter 2.
How many chapters are there?
Six at A1. Chapters 1 and 2 are free here and in the app; chapters 3–6 are part of Contos Premium.
Is it a dark crime story?
No. It's a cosy mystery about missing socks in a block of flats, with a warm, sad turn in chapter 2.
Is the story told in the past or the present?
In the present, in both chapters: polite ます and です forms throughout, even when chapter 2 opens the next morning with Shizuko thinking back. The past appears only in small pieces such as 昨夜 見た こと (what she saw last night).
