Quick answer
A first edition of Partners in Crime by Agatha Christie (Dodd, Mead and Company, 1929) is identified by: US Dodd, Mead published August 1929 (277 pp); UK Collins followed 16 September 1929 (256 pp). The US Dodd, Mead edition (August 1929) precedes the UK Collins edition (16 September 1929) by about a month, so Dodd, Mead is the true first edition.

- Late 1976 onward: a sequence of numbers on the copyright page with '1' present indicates the first printing.

How to verify your copy, step by step
- Find the copyright page — the verso (back) of the title page.
- 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.
- Verify this is the US true first — not a later-market or reprint edition.
- 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.
- 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 US Dodd, Mead edition (August 1929) precedes the UK Collins edition (16 September 1929) by about a month, so Dodd, Mead is the true first edition. This is one of several Christie titles of this period that appeared first in America. The original record's claim that UK Collins is the true first is incorrect.
Telling it from reprints & book-club editions
Later printings and book club editions follow; on the Dodd, Mead first there is no printing statement on the copyright page.

How do I tell the first printing from a later one?

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.
