The Watson Watch

The Case of the Jade Dragon

A shop that robbed itself. A camera that saw everything and knew nothing. A detective who has been bored for a hundred and thirty-one years.
Sam Wong-Watson is eleven, lives above her family's noodle stall in Sai Ying Pun, and writes down things that don't add up. On the night of the typhoon she finds a silver pocket watch in an old trunk and steps out of her storeroom into London, 1895. A Hong Kong mystery for readers 9–12.

一間自己打劫自己嘅舖頭。四部乜都影到、乜都唔知嘅閉路電視。一個悶咗一百三十一年嘅偵探。
阿 Sam 十一歲，住喺西營盤家人嘅大牌檔樓上，有本簿專記「唔合理嘅事」。打風嗰晚，佢喺舊皮篋搵到一隻銀懷錶，一踏出雜物房，已經係 1895 年嘅倫敦。英文原創，特別為香港 9–12 歲小朋友寫得清清楚楚。

Sai Ying Pun, typhoon day西營盤 · 打風日

Every Hong Kong place in the book is real. Holmes asks; a local kid answers. No footnotes.書入面每個香港地方都係真。福爾摩斯問，本地小朋友答，冇註腳。

A machine that steals會偷嘢嘅機器

Four cameras, one delivery robot, a jade dragon gone at 3:14 a.m. The crime was checked by a retired-detective-style read before we called it finished.四部閉路電視、一部送貨機械人、凌晨 3:14 消失嘅玉龍。成件案經過「退休 CID」式審讀先算完成。

Sam closes every case每一單案都係 Sam 破

Holmes explains. Sam notices. Sixteen black-and-white illustrations and a "What Was Real" section at the back.福爾摩斯負責解釋，Sam 負責留意。十六幅黑白插畫，書尾「What Was Real」講返邊樣係真。

Twelve hollows. Two filled.錶蓋十二格，而家填咗兩格。

The watch only opens onto cases nobody ever solved, and it will not take Sam home until one is closed. Each book etches one symbol inside the silver lid. Readers fill the lid with her.隻錶只會開去從來冇人破過嘅案，未破案就唔會帶 Sam 返屋企。每一集喺銀錶蓋刻一個記號，讀者同 Sam 一齊填滿佢。

Book Two is out: The Case of the Pharaoh's Mask. The Valley of the Kings, 1923. Seven padlocks, one steel door, and the gold mask is gone.第二集已出：The Case of the Pharaoh's Mask。1923 年帝王谷，七把鎖、一道鐵閘，金面具不翼而飛。

Book Two reads on its own, but the watch makes more sense after Book One.第二集可以獨立睇，但睇完第一集先會明隻錶。
