No, the Little Lady Killer is a fictional character. Therefore, he is not real.
In which tome?
Yes, the lady killer killed Mack's daughter, I love that book :D
I believe you are refering to a fictional character from the story "The Shack". Sinse I only deal with true crime this one is out of my league.
Well first you can check if they have an Adams Apple (the lump on a mans neck),then you can look and see if they have hips. Hour glass body figure.
