In itself Jasper’s scarf seems inconspicuous. Mr Dickens notes, on the day of Edwin’s disappearance, that ‘The mere mechanism of [Jasper’s] throat is a little tender, for he wears, both with his singing-robe and with his ordinary dress, a large black scarf of strong close-woven silk, slung loosely round his neck.’ After parting with Crisparkle to meet with Edwin and Neville, Jasper ‘pauses for an instant in the shelter to pull off that great black scarf, and hang it in a loop upon his arm. For that brief time, his face is knitted and stern.’ While the gravity with which Jasper attended to this scarf is unusual, it is hardly incriminating, were it not for the subsequent testimony of Sir Luke Fildes, who claims that the scarf is none other than the murder weapon. Could Fildes be right? With only two sentences describing it, what other items of interest have been overlooked in the mystery that may prove equally significant?
