Poison help?

[deza.livejournal.com]

I am looking for a poison that fits a rather stiff set of requirements.

1. Onset time of 45 minutes or less
2. Easily available around an average household
3. Won't be detected in a chocolate-fudge brownie
4. Produces minimal or no vomiting

I'd originally planned to use antifreeze, but from what I've found so far the onset time is around 2-3 hours, and I need to kill my character a little quicker than that. I'd prefer not to use arsenic or cyanide, as they both cause large amounts of vomiting and my MC really doesn't have time to clean up that much mess.

Any suggestions?

How set are you on the brownies?

Phenol (found in comet) or Carbolic Acid (same thing, different name)

Also, can be countered (cured) with strong liquor, like a good brandy with the brownies :D, so that could be your out, the deceased wouldn't drink as much as the MC expected :P

Also, things are still going to taste a little funny, so the uber-creepy poison specialist suggested making them kinda bitter (too much bitter chocolate) and putting Lilacs on the table, because the smell they give off actually deadens a human's sense of smell and taste, so they'll be less likely to taste anything funny. Perhaps just lilac room spray?

Anyway, the effects of the acid are pretty fast. Face turns extremely red and victim feels painful burning all over body, then they asphyxiate, i.e. 'smother' because their blood vessels can't transfer oxygen to the cells, so the vic's reaction would be much like smothering, and they would die in about 20 min. Could be an intense 20 min, too, with the MC trying to pour liquor down the throat of a person that feels they can't breathe . . .

Cabolic acid--Dame Agatha used that one in a nose spray in Death on the Nile :)

The MC injected the poison into some brownies she made the night before--she actually wasn't expecting the victim to accept her invitation to come out and talk.

Yes, my MC is a flake. A likeable flake, with a body cooling on her kitchen floor.
