A fictional book about a Scotland Yard assistant, to the head of Scotland Yard. The time period is around the very early 1900's.
The reader of this book is Ruth Golding. Her vocal range for the voices she gives to the different characters, is amazing! The audiobook is worth listening to, just to enjoy listening to the voices of the different characters!
