Already own Killer Letters Vol. 1? Continue the investigation with Vols. 2–6 and save compared with buying them separately.

You found the first pattern. Now the files start connecting.

Across five more volumes, the cases grow stranger, warnings surface, and details that once looked ordinary begin to feel deliberate. Every grid is still a crime scene: find the suspects, evidence, weapon, and location; identify what appears twice; then use the leftover letters to name the victim.

But the deeper mystery is only beginning. Someone has been hiding in the letters all along, and the truth will not reveal itself until the final file.

This continuation bundle includes:

• Killer Letters Vol. 2
• Killer Letters Vol. 3
• Killer Letters Vol. 4
• Killer Letters Vol. 5
• Killer Letters Vol. 6

Hundreds of solvable cases. A full answer key in every volume. One mystery racing toward its final grid.

Find the words. Catch the killer. Close the case.

A note on shipping: Every book is printed in and shipped from your own country, whether you're in the US, Canada, Australia, or the UK. For almost every order that means no international shipping and no customs fees. What you see at checkout is truly all you'll pay. Postal rates in some countries (looking at you, Canada and Australia) do run higher than any of us would like, so if the shipping on your order feels steep, our Printable Editions are the same puzzles as an instant download in our large print size, with nothing to ship and nothing to wait for.

Canadian readers, one exception. Our Canadian printer cannot produce the Large Print paperbacks, so those orders ship from the UK by FedEx. They take longer to arrive, and customs charges may be collected at your door on delivery. If you would rather skip both, the Printable Editions are the same large print puzzles.
