Taking his car from the garage, Holt starts toward Rosebank, but
turns aside to buy candy, which he has packed in boxes that imitate
books. He purchases two novels. To one who recognizes him, he
pretends he is looking after bank property. He reaches Rosebank; he
enters the house of the willow walk, removes the candy to the paper
wrapper, and places the two imitation books, with the novels, on the
bottom shelf of the book-case. (Incidentally, he makes use of the
principle exploited by Poe in “The Purloined Letter.”)
