"Good work? You're going to turn him into another bloody Murdoch!"

[George is stood in his room. If it seems more well lit than usual...it is. Because ghosts can't haunt you in the light; too see-through.]

I think the obvious solution is to hold one to several seances. Whom on board is the most sensitive?

We might also try to catch one of the spirits mid-haunt and try to communicate with it there, but that would require everybody turning out their lights and being quite quiet, luckily, rather late at night. Would anybody else be interested in taking part in such an investigation? ...because I wouldn't like to undertake one alone.
