The Mystery of Collinwood

They left Barnabas off the cover since he's not in the story, unlike a couple of other covers.

Victoria is still in love with Earnest Collins who is away. Margaret Lucas is a woman who has rented a small cottage from the Collins and has a servant named Carlos.

Professor Veno and his daughter come to the house to stay for a bit. (There are a number of events that repeat very closely events in the novel Victoria Winters, and this is the first of them.)

Linda looks like Victoria (another repeat). Linda also knows Earnest and is interested in him. Elizabeth likes Veno and Roger dislikes him (another repeat).

There's a story about the Phantom Mariner and, if you see him, you will die soon. Victoria sees the phantom (as in the other book she saw what she took as the ghost of Stella.)

Victoria and Burke Devlin have a lot of conversations in the book. Victoria is suspicious of the professor, but Elizabeth takes his side (yet another repeat).

(Another point I'm wondering about. If the cliff is so dangerous, why hasn't a tall fence been put around the edge of it?)

Victoria runs into trouble in the cellar (another repeat) and there are many attempts made on her life. The professor has developed an early form of taser by putting batteries in his cane and rigging it up so it gives off an electric charge.

We also find out that at least two of the people in the story are not at all who they claim to be. It's a decent mystery although there is too much repetition of events from the other novel.
