it is a hobby of mine to have an exact knowledge of london. there is mortimer’s, the tobacconist, the little newspaper shop, the coburg branch of the city and suburban bank, the vegetarian restaurant, and mcfarlane’s carriage-building depot. that carries us right on to the other block. and now, doctor, we’ve done our work, so it’s time we had some play. a sandwich and a cup of coffee, and then off to violin-land, where all is sweetness and delicacy and harmony, and there are no red-headed clients to vex us with their conundrums."
