A young lawer and guest
Back in school, he was the boy that put the tacks on his professor's chair. Full of himself. A gambler and a liar. He has a dry, sarcastic humour and a sharp mind, which coupled with a quick tongue made him very much a poster-boy of his profession. Does not gladly suffer fools, but also has a tendency to make one of himself due to his chronic lack of tact and affinity for pretty, wealthy women. Eternally caught up in his own cleverness, he often tangles himself up in his own elaborate webs of lies and comprimises - backing himself into corners and not realising until too late. Lucky he has such an excellent poker face.
The only weapon he carries is a simple penknife in his left breast pocket.
Relationship to Host; On the outside (VERY) distant relation of Isaac Baxter, currently boarding at the manor by the Lord's charity (While well connected, Mr. Adams is not rich). On the inside, however, he is also Maude Baxter's lover.
Motive; Not very long before she died, Charlotte uncovered the affair between himself and Maude Baxter. Needless to say, had Isaac heard of the affair Mr. Adams would have no longer been welcome in the Baxter household and would have been out on the street, without a penny and nowhere to go. You can put the rest together.
