The Suspects

  • Mr Hollis

    Stationmaster, fifteen years at Earlsfield

    A spare, deliberate man of fifty, who held the strongbox-key on a chain at his waistcoat. He had not had a holiday in three years; his quarterly leave was due in February.

  • Mrs Hollis

    Wife of the stationmaster, lived above the booking-hall

    A composed, careful woman of forty-eight, twenty-three years married. She kept her husband's chatelaine of small keys and had her own daily rhythm of morning chores within the booking-hall.

  • Mr Lapworth

    Porter, three years at Earlsfield

    A heavy young man of twenty-six, with a small standing debt at the village inn and a Friday evening's habit there. His pay was modest; his lodgings cheaper.

  • Mr Brewster

    Commercial traveller, regular weekly lodger at the station-inn

    A bluff, obliging man of forty in haberdashery, who took the inn's first-floor room every Tuesday night and was the only outsider to the village familiar with the Halt's takings-day. He had business in Haslemere on the Wednesday morning and back to Waterloo by Thursday's noon.

Section III

The Evidence

  1. The intact strongbox

    The strongbox bore no mark of forcing; no scratch upon the lock-plate; no key-mark within the wards. The box had been opened with the proper key and shut again, time after time, through the half-year.

  2. Mrs Hollis's chatelaine

    Mrs Hollis carried, by long habit, a chatelaine at her waist with the small keys of the booking-hall larder, the upstairs press, and the porter's locker. Holmes asked, with a quiet courtesy, to see the chatelaine; the strongbox-key, he observed, hung from a small ring at one end of the chatelaine, beside the larder-key, in the polished brass of long use.

  3. Mr Lapworth's standing debt

    The porter's standing debt at the Three Foxes was three pounds two by the inn-keeper's slate. He had not paid down anything of it since Easter.

  4. Mr Hollis's overdue holiday

    Mr Hollis's leave-record showed him three years without a holiday. Mrs Hollis had spoken to him, more than once at the kitchen-table, of a fortnight at Brighton in February for their silver-wedding anniversary.

  5. A small private savings-book

    Holmes asked Mrs Hollis, with the rector of the parish present, whether she kept any private savings of her own. She produced a small post-office savings-book in her own name with a balance of forty-nine shillings and threepence - accumulated, the entries showed, at two shillings a week from May.

Section IV

Statements & Testimony

  • Mr Hollis Reliable

    Stationmaster

    “"The key has not left my fob, Mr Holmes. The box is in my office; the office is mine. The takings are counted on Saturday and locked away. I have noticed the discrepancy these six months and I have blamed it upon my own miscount. The takings are not large; the loss is steady."”

  • Mrs Hollis Reliable

    Wife of the stationmaster

    “"Of course, sir. The chatelaine has the larder-key, the upstairs press, the porter's locker - and the strongbox-key, which my husband had cut for me at his last leave four years ago, that I might take down a sovereign for the doctor in the night if it were needed."”
