"Excuse me", Galtheyn says.  He fishes a black rectangular object out of 
his pocket, about the size of a CD case, and holds in front of his face.

"Hello", he says, speaking into it.  There's a voice coming out of it, 
but neither Hank nor Roy can make out the words.

"I'm showing them round the workshops", he says.

The think speaks again.

"Right....  OK... ".

"Duplar's coming down to see you two", he says to Hank and Roy.
