Transcriber’s Notes

This transcription follows the text of the 1927 edition, as reprinted by Penguin Books, with the exception of the chapter names, which were omitted in that edition. The ebook reprint by Orion House was consulted to restore the original chapter names.

The following alterations have been made to correct what are believed to be unambiguous errors in the Penguin Books edition:

Additionally, several occurrences of unpaired quotation marks have been corrected. Lastly, in Chapter IV a single line of dialogue (“Can you guess what poison was used?”) was erroneously omitted. It has been reinstated here (obtained by consulting the Orion House ebook).

Other errors, if any, in the Penguin Books edition have been left as printed.
