It was a dull evening in the month of September, 1728. The apprentices had closed and barred the shutters and the day's work was over. Supper was laid in the long room over the shop, the viands were on the table, and round it were standing Bailie Anderson and his wife, his foreman John Gillespie, and his two apprentices. The latter were furtively eying the eatables, and wondering how much longer the grace which their master was delivering would be. Suddenly there was a knock at the door below. No one stirred until the bailie had finished his grace, before which time the knock had been twice repeated.
