" I am getting old, Russell. Gone are the days when I could scramble about on the moors all day and curl up happily at night with a thin blanket and a stone for a pillow. Three nights on floorboards and one night without sleep following three days at strenuous labour make me aware that I am no longer a callow youth. "

― Laurie R. King , A Letter of Mary (Mary Russell and Sherlock Holmes, #3)
