Sweet Angelica

it was the teacher paul dunne.
felix the handyman was black mailing him.
paul dunne used too be in the army, but was thrown out in disgrace for attacking a fellow soldier and leaving him in a serious condition.
felix somehow found this out.
he changed his surname and became a teacher at the school.
he then killed angelica because she was going too inform the police.
he said he loved angelica, but couldnt have her blabbing.
his alibi of being at some concert 30 miles away was proven untrue as a newspaper reported that the concert had been cancelled.
and the estate used too grow pineapples years before and the compost used back then was still in the soil and causing the grass too die.

if you send me a pvt msg i will give you a site where you can watch that episode again, so you can see it for yourself.
