Horst Gets Questioned

"This is the third letter I've received as of today," Horst said while looking on at Mews and Quigley over a pot of Irish Breakfast. 

"And the others?  Do you have the first two letters?" Horst shook his head.

"Sadly no," he said.  "I tore them up and tossed them in the trash," Horst said with doleful eyes.  "At the time, I felt that was the best place for them."  Mews wasn't sure but he thought he saws some tears welling up.

"Right, well, what's done is done.  Let's review what we know.  There have been three letters-the first two handwritten, and now this one.  The first two said "Get lost Dog."  Mews shakes his head.  "I don't like the fact that this one is not handwritten."

"And why is that Mews?"  Quigley asked.

"Well, not only does it evoke a sort of ransom note, but it suggests that the perpetrator might be taking further steps to disguise his or her identity.  If that is the case, it might suggest that they are in fact not finished with their campaign.  Of course this is all speculation.  What else do you have to add Horst?"

"A thud." 

"Pardon?"

"Yes, I'm sure I heard a thud right before I opened the door and found the letter."

"Yes, all right.  A thud.  Make note of "a thud" Quigley, won't you?"
