During the 1974-1975 school year Monagham Hall was the site of many unusual occurances. Footsteps in an empty building, an organ playing by itself, and a growling noise in the basement.

Many of the students said they were frightened to go into the building because of "the footsteps." Father Leedale decided to spend a night in his office in order to put the students fears to rest.

One evening he went to open a classroom door, but before he could put the key in the lock the handle turned and the door opened by itself. There was no one in the room.

A housekeeper, who had went back to the Hall to get some things that she had left there, found the front door unlocked and when she went inside she heard organ music playing. The same stanza played over and over again. She thought that someone was practicing but the door was locked and there were no lights on. She got the key and entered the room. The organ kept on playing; the keys were being pushed down in time with the music. She checked the window and it was closed and locked from the inside. She ran from the room and the building.

Two months later Father Leedale heard a flute playing outside his door. When he looked out the music stopped. A couple of weeks passed and he was still puzzled by the music. He went to his piano and played the same tune that he had heard that night. The housekeeper came knocking at the door and told him that it was the same music she had heard coming from the organ back in November.

In February of 1975 Father Leedale, two security guards, and two other men went through all the rooms on each floor and didn't find anything amiss. Father Leedale went back to his studio and the others left. When they got outside one of the guards said that something was moving in a third-floor window. They returned and did another check of the building and there wasn't a soul around.

As they were leaving and entered the hallway the men were stopped by a "force". One guard said it felt like he was being strangled. The other guard's skin tingled, and Father Leedale said his skin "reacted to something that was present." The two other men said that they had difficulty moving and felt overcome by an "oppressive presence." One of the guards, who remained anonymous, told the press, "I know what I saw, I know what I heard. And you couldn't pay me to go back in there again."

Father Leedale knew the fear that he felt. The week before he and a student were checking out the basement when they heard a "growling" noise coming from inside a locked room. When he went inside all that he found was an old, stringless, bass viola.

Father Leedale, having had enough of the presence, started a four day prayer session to exorcise whatever it was that was in Monagham Hall. By February 28, 1975 he was successful and the strange occurences never happened again.
