Figuratively, ‘running with hare and hunting with the hounds’ is the deceitful
behaviour of one who fights of one who fights on one side and gives secret
help to the other side. Terms for these traitors to the cause are ‘double-
dealers’ and ‘double-crossers’. A very old saying, dating back to the
fifteenth century, is: ‘Thou hast a crooked tongue, holding with the hound and
running with the hare.’ Invariably these tricksters are found out; they should
be loyal to one side or the other.
