‘Quenched by quotidian drudgery’

River had never met him. He’d quit Slough House months before River’s arrival; one of those in whom the fire that had driven him into the Service had been quenched by quotidian drudgery. River had no idea what failure had landed Black in their company. Asking would have been like dredging up ancestral sins; enquiring which wicked uncle interfered with which parlour maid. More than that, it would have required River to care, and he didn’t.
