The poem "The Highwayman" by Alfred Noyes tells the story of an unnamed highwayman in love with Bess, the daughter of a landlord in one town. But a jealous man Tim alerted the authorities about the highwayman and their relationship, betraying them.
In the second part of the poem, when the highwayman returned, the now captive Bess tried hard to warn him of the ambush waiting for him. But unable to do so subtly, she took the gun and shot herself, which was enough to ward off the lover and he took away, returning the next morning where he was also shot dead. In order to save her lover, she had sacrificed her life. But they reunited in the afterlife.
