The time window may be bigger then we realize. BH spoke on the phone to someone (maid?) at 10 am on the morning he vanished. That is the last time someone other than the SIL can verify BH was alive and at the house.
Because there was a meeting that got "heated"the night before between BH and his daughters, I will not use the daughters or the SIL as a means to make a timeline.
Furthermore, the fact that one of the daughters volunteered that there were "no threats" at the meeting is disturbing to me.
I'm wondering if, or how well have you known Mr. Harrod, or his wife, or her family, or Mr. H's family, or the barber lady? Was Mr. H a good friend of yours, to know how/what he would have or have not been thinking?
Is it that you have a direct connection and are not able to see beyond the foul play theory, while everyone else has considered and discussed all foul play and voluntary missing possibilities. Perhaps nobody has a true clear picture of Mr. H's thinking at that time. I am not convinced either way, based on what has been written by others. Is there true factual information you can share to help others understand your interest in this disturbing disappearance of Mr. H. To understand your viewpoint could stimulate thought for others to help solve a mystery. Please share. Thanks!
