MacDunn is a large, white-bearded man who has obviously spent too long sat at a desk or stood at a lectern in a classroom, his belly quite large. As Lillian speaks, he looks at Dr Walker, seemingly confused as to why his secretary appears to be speaking instead of the man himself, but appears to shrug it off quickly. When he speaks, it's with a deep Scottish brogue, his words spoken somewhat slowly and mellifluously, as if rolled around his mouth first to savour them before being uttered.
"Ayers?" he begins. "Haven't heard that name in a while. Here, sit ye selves down," beckoning to a couple of chairs in his quite spacious office. He leans back in his chair to stare at the ceiling, tilting it at a quite alarming angle, enough that both of you fear he's going to tip it over, but it appears this is something he's used to and his belly provides the necessary ballast to keep him stable.
"He's been gone since, what '24? I remember I gave him permission to travel to Africa for a year, some dig he was interested in. I told him he'd need a private donor to finance his trip, and he came up with one straight away, was a little surprising as these things tend to take up some time. Name's on the tip of my tongue, a local businessman. What was it now? Mexican name."
He spends some time in thought on this matter, giving you the opportunity to jump in if you wish to.
