Thanks for the feedback.
I've just uploaded a patch to solve both bugs you reported.
But most importantly, who's your favourite suspect?
That's great. I noticed the same responding error another time two suspects were in the same room, though maybe the patch has covered any incident when two characters are in the same room.
Little suspicious of Wife, considering what I found in the kitchen, but I think there is a lot I have yet to find. I guess my favorite suspect is the gardener, who seems quite literally down to earth, but who knows what secrets he may have...
