The Long Halloween
Gilda Dent and Harvey Dent both carried out the killings of Holiday but without the others knowledge. Gilda is revealed as one of the killers when she is seen burning the gun that Holiday used and the disguise that Holiday used. It is unknown how many people she killed by herself and how many Harvey killed by himself. Harvey supposedly did this so that he and Gilda could start a family.
