A character says "I ate my last Trump and Fotheringay pie months ago" a google search resulted in nothing helpful so I suspect it may be cockney English for something else. The problem is I haven’t the foggiest idea as to what it could be.
Trump and Fotheringay, like Murgatroyd, are brands of food in the Neath. Murgatroyd has fungal crackers (and an alarming number of other products), while Trump and Fotheringay seem to be famed for their Esteemed Meat Pie, available (in the fiction, unfortunately not in-game) for the discerning pie connoisseur in London.
