Shriekville's Ghostsall logic puzzles

Five people were all taking a vacation in Shriekville, unfortunately, all of their vacations were cut short by a terrifying encounter with a resident ghost.

Can you determine the type of accommodation, its name, and the name of the resident ghost?

Archibald stayed at St George's, he was not frightened off by Macabre Malcolm.
The public house was the home of Chilling Charlie, who frequently turned down the thermostat and then let out gruesome shrieks, chilling everyone to the bone.
Lucas or Archibald's vacation was at the castle. Was Terrifying Tony the resident ghost there?
Charlie went to stay with friends, this was in a bungalow, but it did not have the name Briar Hill. He was not terrified by Bloodcurdling Brian, the ghost that left bloodstained footprints behind.
Billy vacationed at a place named Rosedale, which was not a hotel.
Creepy Craig really did scare Gary, as he was settling down to sleep, by scraping his fingernails on the bedroom window, this was not at a hotel, and it wasn't a place named Avalon.
The bed and breakfast accommodation was not High Lodge, which was also not the castle where Macabre Malcolm was resident.

Puzzle 200 


Below is a very special grid, around each shaded number are 8 white squares.

However, each white square should have a number from 1 to 7.

Once filled in, these 8 numbers will sum to the shaded number.

In addition, once completed correctly, no row nor column will contain a duplicate number within a white square.

For example, the top row may be 5 6 4 2 3 1 7, etc.

This is a very difficult puzzle, and many people resort to using a computer to help them, which is a challenge in itself.
