Before you buy, be the detective.

A missing cash-box. A helpful guest. Two documents that do not agree. Everything you need to investigate is below.

Case 013 · Paper trail

The Sunday Train

Netherford, October 1936 · Easy · Book estimate: 10–15 minutes

Read the scene and inspect both pieces of evidence. Make your accusation, then open the hints or solution when you’re ready.

The Station Hotel at Netherford kept two things with religious care: its register, and its opinion of itself. When the office cash-box went missing between Sunday supper and Monday breakfast — forty-one pounds and the Christmas Club money — the proprietress produced the register for the constable like a churchwarden producing the parish rolls.

Only one guest had arrived that Sunday: a Mr. J. Carew, who had signed in the neat, forward-leaning hand of a man used to signing things, and who had been all sympathy at breakfast. “A bad business,” he told the constable. “I came in off the London train last evening, took my supper, and slept like the dead — heard nothing. You’ll want my particulars; they’re in the book.”

They were. Here is the page.

THE STATION HOTEL, NETHERFORD · VISITORS’ REGISTER · 1936

DOCUMENT IN EVIDENCE · 01

DateNameAddressArrivedRoom
Fri. 16 Oct.Miss E. ProwseCheltenham4.10 p.m., per motor-coach2
Sat. 17 Oct.Capt. & Mrs. R. HoltShrewsbury6.55 p.m., per 6.30 ex Birmingham4
Sun. 18 Oct.J. CarewLondon, W.8.40 p.m., per 8.15 ex London6

And here, for completeness, is the framed notice that has hung in the hotel’s hall, beside the barometer, since the last week of September — as it hangs in the booking office across the road:

NETHERFORD BRANCH · NOTICE TO PASSENGERS
G.W.& M. RAILWAY

DOCUMENT IN EVIDENCE · 02

WINTER SERVICE from 28th September 1936. Weekday trains from London call at Netherford at 10.02 a.m., 1.44 p.m., 5.31 p.m., and 8.40 p.m. (the 8.15 departure). Passengers are reminded that there is NO SUNDAY SERVICE on this branch between the last Sunday of September and Easter. Sunday travellers are directed to the main line at Bishopsford, seven miles.

YOUR CHALLENGE

Read the two documents against each other. What is wrong with the register — and what does it tell the constable about the sympathetic Mr. Carew?

Name your answer aloud before revealing the solution. No typing or sign-up needed.

Hint one · A nudge

The register is honest about everything Mr. Carew wrote in it. Check the one column where his entry makes a claim the other document can answer.

Hint two · A stronger push

What day of the week did Mr. Carew arrive — and what does the framed notice say happens on this branch on that day of the week, from the end of September?

Reveal the solution & reasoning

His claimed train arrival does not fit the timetable.

Carew’s entry says he arrived on Sunday, 18 October, at 8.40 p.m. by the 8.15 train from London. But the railway notice says there is no Sunday service on the Netherford branch during that period. That train and its arrival belong to the weekday service.

The contradiction comes from comparing the two documents. His helpful manner at breakfast proves nothing; the arrival he put in writing is what the constable can challenge.

The Examiner’s lesson

Read one document against another. The register contains Carew’s claim. The timetable supplies the fact that contradicts it.

A false arrival is not proof of theft.

Carew may have concealed his route, a travelling companion, or an earlier arrival for another reason. The book’s optional follow-up asks you to suggest an innocent explanation. The evidence gives the constable a lead to investigate; it does not establish who took the cash-box.

Scene, evidence and hints from Case 013. Solution condensed from the book’s explained verdict and follow-up, pages 158–160.

That was one case. Nineteen more await.

That was one of the short ones, ten to fifteen minutes on the easiest rung. From there the cases add suspects, false alibis and the mistakes a killer cannot take back, up to five Unsolvables that run past thirty minutes each. The complete book includes this case and nineteen others.

Before you order

A few practical answers.

Is this a physical book or a digital download?

It is a digital download. No physical book will be shipped. You receive the complete 188-page casebook PDF and print-friendly files. Read on a computer or tablet, or print the pages you want.

How do I get the files after buying?

Checkout takes place on Etsy. Once payment is confirmed, download your files through Etsy in a web browser. If you check out as a guest, the download link is in your receipt email. Etsy’s app does not currently support digital downloads; use your phone’s browser or a computer.

Do I have to print the whole book?

No. The digital edition has a clickable index and links to hints and solutions. If you prefer paper, the print-friendly files include two-to-a-page cases, separate solutions and worksheets, so you can print only what you need.

Is the free case included in the twenty?

Yes. The Sunday Train is Case 013 from the book. This page includes its scene, both evidence documents, two hints and a condensed explained solution. It is one of the easier cases, picked because a short one fits on a web page, and the book climbs from there. Your purchase contains the full version and nineteen other cases.

What if I get stuck?

Every case has two optional hints, followed by a fully explained solution at the back. Begin with the seven easier cases or choose a case by format and difficulty from the index. No outside research is needed.

How does the scoring work?

A full solution without hints earns three marks; a full solution after one or both hints earns two. Certain partial answers earn one mark, as explained in the solutions. Record your marks on the Warrant Card and work towards one of five ranks, from Constable to Consulting Detective.

Is it graphic or gruesome?

Thirteen cases involve murder, handled as classic detective puzzles. The emphasis is on clues and reasoning rather than graphic description. Choose cases appropriate for anyone you are reading with.

Do I need an app, subscription or internet connection?

You need internet access to purchase and download the files, and a PDF reader or browser to open them. There is no subscription or additional Sunday Classics account. Once downloaded, the cases, hints and solutions can be read offline.

What if the book isn’t for me?

Sunday Classics offers a 30-day refund promise. Contact us through your Etsy order within 30 days of purchase and we will refund you. This is our seller promise, separate from Etsy’s standard digital-item policy.
