She is an Angel

She is an Angel is a poem found in Room S11 on the third floor of the Otherworld Brookhaven Hospital in Silent Hill 2. The poem is a subtle clue for the Lady of the Door puzzle, which in order to complete, two objects mentioned in the poem are needed.
 * The first item is related to the "Bridge of Thread" stated in the poem. Once obtaining the copper ring, James Sunderland can examine it and see that it has an engraving of a spider, which creates "bridges" with their silk.
 * The second item is referred to as the "bloated and ugly corpses" of sin. After obtaining and examining the lead ring, it is clear that the bloated face engraved on the ring is what the poem alludes to.
