The Silent Cuckoo: Detective Simulator

Eldridge, 1928. A boy is missing, a threat letter smells of an old closed case, and a knitted cuckoo hangs from the envelope. Fog, gaslight, and a city full of liars — detective, the door just knocked.

The Silent Cuckoo

Eldridge, northwest England, winter 1928. A port city of theatres and smoke, where the upper crust dances at the Silver Finch and the East End swallows people whole.

Late one night, the manager of the Silver Finch Hotel knocks at your door on Claremont Street: his five-year-old grandson has vanished, and an anonymous letter arrived — with a small hand-knitted cuckoo tied to it. The handwriting, the verse, the bird… they match a boy's case from Gaslight Row that the police closed in a hurry months ago.

Two cases. One thread. And nobody in this city tells the whole truth.

  • 🗺️ A clickable city map: twenty locations across four districts — knock on any door, but every visit costs time
  • 🔍 Investigate scenes Holmes-style: clues hide inside the prose; pin physical evidence and spoken leads to your corkboards
  • 🧑‍🤝‍🧑 A live suspect board: motives, alibis and suspicion that move as you dig — and witnesses who lie
  • ⏱️ Three periods a day, two actions each — the trail cools if you dawdle
  • ⚖️ When you're ready, walk into Thames Precinct and make your accusation. Right or wrong, the truth comes out — and gets graded.

A fair-play whodunit: everything you need is findable. Whether you find it is another matter.

Characters

👮
Sergeant Wilfred HenryThames Precinct — your old friend

A broad, talkative sergeant who has survived twenty years in a crooked precinct by knowing exactly which doors not to kick. Loves his suppers, loves a good yarn, and quietly keeps one incorruptible line: nobody touches ordinary folk on his watch.

📓
Robin PageYour assistantCustomizable

Early twenties, shorthand faster than most typists, and a memory for timetables. Came to 221B answering a three-line advertisement and never left. Steadier than they look when things turn ugly.

🧢
Constable Tommy WhitakerRookie constable

Nineteen, polished boots, asks the question everyone else is too proud to ask — which is occasionally the right one. Worships the Sergeant; terrified of the coroner.

🎩
Theodore FosterManager of the Silver Finch — your client

Sixty-one, silver-haired, the West End's most courteous host. Tonight the courtesy is cracked: his five-year-old grandson is missing, and he has come to a private detective at midnight rather than to the police. Odd, that.

⚕️
Dr. Edith MarshCoroner, Granville Infirmary

Precise, unsentimental, smokes thin cigarettes between autopsies. The only person at Granville who writes down exactly what she sees — which has made her unpopular with the board.

Win / Lose

The case ends only at a formal accusation at Thames Precinct (or if the player abandons the case). Correct culprit = game.end win, with a grade in the label (及格/良好/优秀 by evidence depth, instigator exposed, and whether the missing boy is saved); wrong culprit = game.end lose — the real one slips into the fog. Either way, the full truth is told only after the ending.
