I was walking past the Garrick Club last week and stopped to admire the grandeur of its façade, now that it is no longer covered in soot and grime.   It was no wonder that I could not identify its architect, a man named Frederick Marrable, a pupil of Blore.   He was architect of the Metropolitan Board of Works, responsible for settling claims, laying out Burdett Road and the design of Holborn Viaduct.   The Garrick is a more than halfway decent piece of Clubland classicism, with its high entrance, its dining room remote from the street and surprisingly good stone detailing:-
