WHO dies ‘accidentally’ in a BATHTUB??? ...druggies aside.. awww, come on!... Really...
I agree something sounds soooooooooo wrong in the third wife's death and the fouth wife's disappearance.
Hum.. I read years ago that if someone’s head is suddenly submerged in a bathtub by pulling upwards on their feet, there is frequently a “startle” response that causes them to breath in.
