"I took elocution lessons, at five bob a time, from a genteel old thing in black velvet and musty lace ... who at intervals in our weekly half-hours together would excuse herself and turn aside demurely to steal a swig from a naggin-bottle she kept hidden in her reticule."
John Banville, Eclipse, p.35
