And more in that vein, until Daniel ducked into the vault of the Great Gate of Trinity College. The gate was a hefty structure with crenellated towers at its four corners: a sort of mock-fortress, just the thing for retreating into when under attack by a Jeffreys. Between it and the side-wall of Trinity's shotgun chapel was a gap in the College's perimeter defenses about a stone's throw wide, patched with a suite of chambers that had a little walled garden in front of it, on the side facing towards the town. These chambers had been used to shield various Fellows from the elements over the years, but lately Daniel Waterhouse and Isaac Newton had been living there. Once those two bachelors had moved in their miserable stock of furniture, there had been plenty of unused space remaining, and so it had become the world's leading alchemical research facility. Daniel knew this, because he had helped build it – was helping build it, rather, for it was perpetually under construction.
