A is a Liar (which means wither they are all liars or there is more than one knight)
B is a Knight (which means that A is the only Liar and C and D are knights)
C is a Knight (which means A or B is E's Fiance)
E may be a Liar or a Knight (In either case this means she is married to a Knight and so B is her Fiance)
