Answer 2

Hmmm, the 24 hours thing is a bit tricky -- if you use a chemical the results are either acute (generally within minutes) or chronic (years or decades). If you use a biological agent (bacteria or virus) you have to deal with the incubation period. And even toxins take time to run through the body and start to have an effect.

But if I had to choose, I'd go with something like botulism toxin, or saxitoxin, or possibly even ricin. Under normal exposures, they might take a couple of days, but a higher dose could kill a bit more rapidly.
