According to some of the book reviews I read on GoodReads, this was Agatha Christie's second novel.

And it shows.

I tried reading the first chapters and couldn't continue. The characters weren't that interesting, the banter between them tedious, and I just didn't want to continue.

So this book earns a formal "No Review" from me because it wasn't fair for me to review a book that I hadn't finished reading.

Perhaps you'll enjoy it more than I did.
