The stories contained in this collection are The Signalman, The Haunted House, and The Trial For Murder. Leaving aside the Kindle edition for now, the first story is a famous classic, and in my view one of the finest ghost stories ever written. It has been anthologised many times, and deservedly so, so you may find it in a collection if you find the other two not to your taste. The second story, The Haunted House, is the real weakest link. It begins quite promisingly, Chapter One being devoted to the narrator and his household moving into a reputedly haunted house, the problems they experience with staff and finally their replacing the servants with a house-party of volunteers intent on solving the problems of the place. They vow only to speak of any paranormal experience at a gathering on the final night of their stay. The second chapter is devoted to the narrator's experience in what was a child's room, in which is related a tale of that child's schooldays. It's a fairly good story, and has also been anthologised as a stand-alone story. But it ends rather abruptly, and so does the Haunted House narrative, without no resolution or continuation. I don't know if the author died before completion, but it reads as if it were meant to contain several stories from the house party, and was terminated after just this one for some reason. Nor is any of it really a ghost story. The final one, Trial For Murder, is, and has also seen publication in anthology form. A predictable story, it holds its own on the basis of the author's descriptive talents rather than the plot. Personally I'm looking for either a decent anthology with the first and last tales, or to find them as one-offs, since I don't feel like giving Kindle room to the second, but others may like it better.
As for the Kindle formatting, it is pretty good, with only a very small number of typos which don't detract from it, and there is an interactive contents page so you can jump to any story of the three.
