That's just her first two novels, which are public domain in the US.

She has eighty books published as Agatha Christie (& a few more under a pseudonym, IIRC).

Her books will be out of copyright in Canada in 2027, and in the EU and most of the rest of the world in 2047. In the US, at least one of her books won't be out of copyright until 2072.

There are about 80 published books, including short story collections. An Omnibus would be about 25MB or more.

You could, of course, but all her books and make your own omnibus. I prefer them as separate volumes.
