Pembury's dislike of musk appeared to be excessive, for, when the chemist had retired into a secret cubicle as if to hold converse with some familiar spirit (but actually to change half-a-crown), he took the brush-case from his bag, pulled off its lid, and then, with the crucible-tongs, daintily lifted the bottle off the counter, slid it softly into the brush-case, and, replacing the lid, returned the case and tongs to the bag. The other two packets he took from the counter and dropped into his pocket, and, when the presiding wizard, having miraculously transformed a single half-crown into four pennies, handed him the product, he left the shop and walked thoughtfully back towards the Strand. Suddenly a new idea seemed to strike him. He halted, considered for a few moments and then strode away northward to make the oddest of all his purchases.
