Mind , talking of black sheep, there is one type I am not sure you would like to have?, you would want to lock your bedroom door and eat out if they were around and that is the females who according to the female presenter of one programme said of them " they took their secrets to the grave with them".
This was a number of wives and mothers who used arsenic to rid themselves of " troublesome" children and husbands , as arsenic was freely available and mimicked a few diseases at the time doctors, who were none too bothered about how the poor died to be honest, just diagnosed a common illness. The programme was on some time ago and I forget what it was called , but it was very! interesting and in the early years of the 19th century , there was a bit of domestic poisoning about, quite a few of these women just did not get caught and they did take their dark secrets to the grave with them , in later years it became easier to catch them.
Black indeed , sometimes a little too dark.
