A Wyntergrave Mystery

You named the killer.
You still don’t know why.

The findings condemn. They never explain.

There is a full account of what was done at Wyntergrave Hall and why — written afterwards, in a cold room, in the killer’s own hand — and it is not in the book, because it would have spoiled every page of it.

Tell me where to send it.

The killer’s complete confession.

The tarn, the ledger, and why it was done twice when once would have served.

The Twenty-Fifth Case.

A second investigation, complete and printable — six hundred names, six findings, one evening.

Both arrive by return, and they cost nothing. No offers, no noise, and nothing you did not ask for — with a plain way out on every message.
