After the Heong Gallery and a brief look at Downing College we had time to hang out and catch up with each other and Susan very agreeably allowed me to get us lost-ish as we half-aimed for the Fitzwilliam Museum. First we went up a dead end street and discovered Hobson House which used to be a fire station and a mortuary we were told by a random man that we got chatting to. We'd been drawn in by the glass roof and as we went in we also noticed a tower of stained glass surrounded by scaffolding which the same man said housed a staircase.
