So I booked it into Sally's and explained to the employee what was going on and that a man was blocking in my car and I had A Very Bad Feeling. Several employees (god bless Sally's alts, I have said so many times) immediately closed ranks, offering to call the police and walk me to to my car.

I got my dye and the man was STILL parked in front of my car so the manager and another employee volunteered to walk me out. Only when he saw me with two other people did he leave, and even then we all very tersely watched him as he went. A third employee came out to tell us he pulled a u-turn and was coming back the other way so all of them stayed with me until he was long gone.

You are transported back in time and into the body of a young noblewoman in the 1400s. Your parents have married you off to an awful, abusive, rapist husband whom literally no one else would marry despite him being very high nobility because he's that terrible. You successfully produce a baby boy and then plan to murder this man for the good of everyone and yourself. Here is the question: do you think you could murder him in a way that is undetectable to the historical people around you? Note: they aren't stupid, you are the prime suspect as the battered wife AND you can't just say poison. Where are you going to buy poison? Do you know anything about poison actually? NO GOOGLING! You were sent back without a plan!

Edit: my notes are full of murder. I love you all

Edit: to clarify about the poison, you can use poison if you actually know how to identify it, I'm saying you can't just go "Poison!" with no knowledge about poison. Buying it probably means they know that poison and you're caught. Your personal knowledge when you read this post is all you have.

Another point of clarity: You went through all that trouble to have a baby without modern medicine so you could get the sweet house after your husband died. That's why you can't be caught. No disappearing.

Edit again: Air embolisms are going on a high shelf because the syringe won't be invented for 350 years. Prove to me that you could make one from scratch, lol

I promise to stop making edits (lol): I left the country vague because I just wanted to see ideas for modern vs. past. Whatever place you are most knowledgeable about
