"The Tomb" tells of Jervas Dudley, a self-confessed day-dreamer. While still a child, he discovers the entrance to a mausoleum, belonging to the family Hyde, whose nearby family mansion had burnt down many years previously. The entrance to the mausoleum is padlocked and slightly ajar. Jervas attempts to break the padlock, but is unable. Dispirited, he takes to sleeping beside the tomb. Eventually, inspired by reading Plutarch's Lives, Dudley decides to patiently wait until it is his time to gain entrance to the tomb.
One night, several years later, Jervas falls asleep once more beside the mausoleum. He awakes suddenly in the late afternoon, and believes that a light has been latterly extinguished from inside the tomb. Taking leave, he returns to his home, where he goes directly to the attic, to a rotten chest, and therein finds the key to the tomb...
