B.P. Walter Books in Order (Updated February 22, 2026)

B.P. Walter (Barnaby Walter) writes standalone psychological thrillers rather than an ongoing series. There’s no shared “book 1 → book 2” continuity to protect, so the main reason to use an order is to track publication history and avoid duplicate purchases under alternate titles.

He also publishes under other names (not covered here), so make sure the byline says B.P. Walter if you’re collecting this specific bibliography.

Three rules that keep you spoiler-safe and wallet-safe

1. Any order works because these are standalones.
2. Edition titles can change by territory, so match the premise as well as the title.
3. If you want to see his style sharpen over time, read in publication order below.

Publication order (B.P. Walter standalones)

1. A Version of the Truth (2019): A family dinner becomes a trigger point for a secret that forces every character to question what they’ve been living alongside.
   • Also published as: The Couple’s Secret (alternate title in some markets)
2. Hold Your Breath (2020): A relationship-based suspense setup where one decision turns a private crisis into a wider, escalating threat.
3. The Dinner Guest (2021): A high-pressure “one night, one table” thriller built around social power, hidden history, and the danger of inviting the wrong person in.
4. The Woman on the Pier (2021): A coastal, emotionally tense story where a single sighting (or misunderstanding) fractures trust and exposes how fragile “normal” can be.
5. The Locked Attic (2022): A suspicion-driven mystery where the closed door next door becomes an obsession, and the act of looking for answers starts rewriting reality.
6. Notes on a Murder (2023): A darker, more intimate psychological spiral that treats motive as a puzzle and memory as an unreliable witness.
7. The Garden Party (2024): A glossy social setting turns sharp, with class resentment and private grudges surfacing under the politeness of a curated event.
8. The Treehouse (2025): A contained, atmosphere-forward thriller where a seemingly nostalgic place becomes a stage for long-buried tension and carefully timed reveals.
9. The Winter Visitor (2025): A seasonal, family-facing crime thriller that uses the “perfect holiday” façade to amplify secrets, suspicion, and consequences.

Recommended ways to read (pick a track)

Track A: “Start with the cleanest introduction to his style”

1. A Version of the Truth → 2) Hold Your Breath → 3) The Dinner Guest
   Why this works: it moves from domestic secrecy to bigger, sharper set-piece suspense without needing any shared continuity.

Track B: “I want social settings that curdle”

1. The Dinner Guest → 2) The Garden Party → 3) The Woman on the Pier
   Why this works: all three weaponize manners, reputation, and what people perform in public.

Track C: “Give me the most recent momentum”

1. The Treehouse → 2) The Winter Visitor → then circle back anywhere
   Why this works: you get the newest tone and pacing first, then backfill by mood.

Title-variant alert (so you don’t buy the same book twice)

• A Version of the Truth is also published as The Couple’s Secret in some editions/regions.

If you see both titles listed, compare the central setup (family dinner + devastating discovery) rather than assuming they’re different books.

FAQs

Do any B.P. Walter books share recurring detectives or a continuing cast?
Not as a formal series. These are designed to stand alone.

What’s the safest first pick if I only want to read one?
The Dinner Guest is a strong “single-book test” because it shows his tension-building and character pressure in a tight, controlled setup.

I’ve seen other names associated with the author, does that affect reading order?
Only if you’re collecting across pen names. This page is strictly B.P. Walter; other bylines represent separate bodies of work.

Bottom line

You can read B.P. Walter in any order, but if you want the cleanest, collector-friendly path: go publication order, and watch for the alternate title The Couple’s Secret.
