The points of issue

Decode the printer’s key: paste the number line into the decoder.

How to confirm the first-printing statement

Publishers stated first printings differently by era. The decisive tells are a printed “First Edition/First Printing” statement, a number line whose lowest number is 1 (Random House ends at 2), or a dated first printing with no later printings listed. Paste your copyright page into the number-line decoder.

How to verify your copy, step by step

  1. Find the copyright page — the verso (back) of the title page.
  2. Confirm the first-edition statement — look for “First Edition,” “First Printing,” or the publisher’s equivalent wording.
  3. Check for a number line or dated printing — the lowest number present is the printing; a dated first printing with no later printings listed is the tell.
  4. Verify this is the UK true first — not a later-market or reprint edition.
  5. Rule out a book-club edition — a blind-stamp on the rear board or a jacket with no printed price marks a book-club copy.
  6. Photograph four things — the front cover, spine, title page, and copyright page — the standard record for identification.

The dust jacket

For a collectible first edition the dust jacket matters as much as the book. Confirm the jacket is present and unclipped — the printed price should still be at the corner of the flap (a clipped corner or a price-less flap can indicate a book-club issue). First-state jackets can differ from later ones in the cover art, blurbs, or review quotations; where a specific first-state jacket point is known for this title it is noted above.

Binding & format

Where multiple bindings exist, the hardcover trade issue is usually (but not always) the precedence copy — confirm against the points above. Later printings often show cheaper cloth, thinner boards, or simplified spine stamping. A simultaneous signed or limited issue, when one exists, is a distinct state from the trade first.

Is this the true first?

The true first is the UK edition: W. Collins Sons & Co. Ltd., London, June 1929. The US edition — Doubleday, Doran & Company / The Crime Club, Inc., Garden City, 1929 — is the first American edition and is separately collected; it was the Crime Club's Christmas 1929 jury selection, placing it late in the year and behind the June Collins publication. Note the confusing double use of 'Crime Club': in this pairing the Crime Club is the AMERICAN imprint, not the British one. The novel is an elaboration of Berkeley's long short story 'The Avenging Chance' (Pearson's Magazine, September 1929); the novel appeared before the story, and Sheringham's solution in the story is discarded in the novel.

Telling it from reprints & book-club editions

The principal first-thus trap is the 2016 British Library Crime Classics edition, which is not merely a reprint: it adds an introduction and new epilogue by Martin Edwards, an alternative ending by Christianna Brand (written for a 1979 US re-release and first collected there), and a further new solution devised by Edwards — a materially different text. Later Collins impressions are noted on the verso; later Doubleday/Crime Club printings are identified by the ABSENCE of the 'First Edition' statement.

Glossary

First edition
Every copy printed from the first setting of type. Collectors usually want the first edition, first printing (the true first).
First printing / impression
A single press run from that setting. The first printing is the earliest and most desirable; later printings are still the first edition but not the true first.
Number line (printer's key)
A row of numbers on the copyright page (e.g. 10 9 8 7 6 5 4 3 2 1). The lowest number present is the printing — a line including 1 marks a first printing (Random House deliberately ends at 2).
Points of issue
Specific physical details — a stated edition, a number line, a typo, a jacket state — that identify the true first printing.
Book-club edition (BCE)
A reprint made for a book club. Tells include a blind-stamped dot or square on the rear board and a dust jacket with no printed price. Not the true first.
First thus
The first appearance of a particular version (first paperback, first illustrated, first U.S. printing) — a first of that kind, not the first edition of the work.
