A month on, the Shaws are still learning tales of its ghostly presence.
Sue Ingram was installed as manager and had worked at the hotel "on and off " for 28 years.
The Rose was murdered in room one for the "little bit money and gold she had", Ingram said.
"The murderer was never found and that's why she's still here."
She said she was convinced of her presence.
"You catch glimpses of her out of the corner of your eye. That happens quite often."
Taps would often turn on and off, room one could be icy cold even when there was sunlight streaming in and there were tales of men being pinned down in their beds, Ingram said.
Gerry Shaw had been outside the hotel with a real estate agent when Ingram approached and asked, "Are you going to buy the place?".
"She got a bit of a shock when I said 'yes'."
The relief Ingram showed was palpable and ended months of uncertainty, Shaw said.
It was a homecoming of sorts for him. His mother was brought up in nearby Cambrian and his cousin owned Cambrian Station.
"I used to holiday on the farm from about age 12."
He was motivated to buy it because he had heard a rumour about it being turned into a holiday home.
"I didn't want that because it really is the heart of the town."
His wife agreed.
"When you think of St Bathans, you think of here [The Vulcan]."
The couple have also bought the cottage two doors up from the hotel and are "tidying it up" as a base for themselves away from the hotel. That "tidy-up" would also apply to the interior of The Vulcan with only cosmetic changes made, Shaw said.
