The toll-house at dusk

An original fiction passage set in the nineteenth century.

Clara reached the toll-house as the rain began. The door moved backwards and forwards in the wind, striking softly against its frame. Inside, a lamp burned beside an open ledger. The final entry ended after the words ‘Received from’, and the pen rested in a shallow pool of ink. A cup near the fire was still giving off a faint curl of steam. Clara called for the toll-keeper, but no one answered. His oilskin coat remained on its peg, although there was no shelter for half a mile in either direction.

Give two details from the passage which suggest that the toll-keeper left the room suddenly.
