HADES

"Down in the vaults of saint Werburgh's lovely old organ hundred and fifty they have to bore a hole in the coffins sometimes to let out the bad gas and burn it. Out it rushes: blue. One whiff of that and you're a doner.
My kneecap is hurting me. Ow. That's better." (U6.609)

The legend of this PC reads: 'St Werburgh's Church, Dublin. In a vault under the chancel lies the body of Lord Edward Fitzgerald.'
