In the short story, "The Chaser" by John Collier, there are 2 main characters. One main character is a love struck man named Alan Austin who is desperate to get the love of his life, Diana, to feel the same way back. The man seeks a love potion, which would make Diana head over heels in love with him after consuming it. The second main character in the short story is the old apothocary who sells the potions. The old man seems intelligent and wise to the younger man, but to the reader, the apothocary can seem like a tricky fellow, who is really trying to get the younger mans money.
