A Christmas Miracle

Rose Marie sat down then looked up at me with an amazed stare.
“What?”
“These letters,” she pointed to my notes.
“What about them?”
“Do you know what they say?”
“No. I heard Morse code being broadcast on my TV last night and wrote out what I heard but it doesn’t make any sense.”
“Oh, yes it does. These letters are saying: HELP ME PRISONER APARTMENT 423. It’s in German.”
