The Scarlet Seed of Death

Jequirity seeds

A small scarlet seed used by jewellers could be an untapped murder tool in the hands of a mystery author.

Jequirity beans, also known as rosary peas, come from the Abrus precatorius bean. These beans contain a protein known as abrin, which is highly toxic to humans. Unfortunately for mystery authors, we don’t know the amount one might need to make another ill. But we do know that symptoms of A. precatorius poisoning might not make themselves known for days.

When symptoms do make themselves known, they may include nausea, vomiting, abdominal pain, and diarrhea that can worsen and become bloody. Patients might also experience fast heart rate, headache, hallucinations, lethargy, seizures, fever, and organ failure. There is no antidote for abrin poisoning.

Terrible for anyone who has unknowingly eaten any. Quite handy for a mystery author such as myself.
