At an early hour on a Tuesday morning in the spring of 1848, a rumour swept through Swansea with the cold bite of a sea wind. Five Irish excavators — “navvies,” as the townsfolk called them — were said to have committed a murder of the most diabolical character. The tale grew heavier with each retelling: two unoffending Welshmen, family men, had been struck down in the night near the Marquess’s Arms on the road to Loughor.

By the time the first curious onlookers reached the cottages, the truth proved worse than the whispers.
