Romeo Montague, in Mantua, received news of Juliet's death from his servant Balthasar — who saw her laid in the tomb and raced to tell his master. He did not know about the potion. Romeo, upon hearing, did not pause, did not question, and did not wait for the letter he had not yet received.
He purchased a fast-acting poison from an apothecary and rode for Verona at once, entering the Capulet tomb before dawn. County Paris was already there, mourning Juliet privately, and drew his sword upon finding Romeo breaking into the crypt. Romeo warned him to leave. Paris refused. Romeo, this correspondent must sadly report, did not lose that fight.
"Here's to my love! O true apothecary, thy drugs are quick."
He drank the poison beside Juliet and died there, holding her hand, moments before the potion's forty-two hours were due to run out.
