WITH YOUR VIEW WE FEEL THAT A POSITION SO CLOSE TO
FLORES IS A RASH CHOICE AND ARE PUZZLED BY THE EXTRA-
ORDINARY SLOW ADVANCE IMPLIED FOR BOTH BI AND DF.
WHILST APPRECIATING THAT ZG WILL PRESUMABLY RELIEVE
ZB AND THAT C 4347 IS TOWARDS BD 9755 IT DOES NOT
SEEM TO FOLLOW THAT THEY NEED MEET ONE ANOTHER. REF.
RECENT EXCHANGE OF SIGNALS ON SUBJECT OF CYPHER BREAKS
DO YOU YOURSELVES FEEL ANY APPREHENSION (QUERY).
PERSONALLY I DO NOT FEEL THAT THERE IS ANY SERIOUS
GROUNDS AT PRESENT FOR SUSPICION.
