Nothing else makes a sentence sound urgent for so little work. Twelve words in capitals, no punctuation to speak of, and a stop where a full stop should be — the form does the acting.
The company banner across the head, the office of receipt, the number of words and the time of handing in, the addressee, the message in capitals and the sender underneath. It is landscape, 210 × 148 mm, so it reads as a form rather than as a letter.
Five skins: a 1920s wire office, an Eastern Bloc post office whose blanks were printed by the ton, a guild slip for the pigeon post with the relay lofts' stamps down the side, an interstellar relay printout on fanfold paper with the dropouts left in, and a fax cover sheet as it came out of the machine. 300 DPI. A longer message that came by post is a Message.
