The Waiting Supper by Thomas Hardy

This laxity of emotional tone was further increased by an incident, when, two days later, she kept an appointment with Nicholas in the Sallows. The Sallows was an extension of shrubberies and plantations along the banks of the Froom, accessible from the lawn of Froom-Everard House only, except by wading through the river at the waterfall or elsewhere. Near the brink was a thicket of box in which a trunk lay prostrate; this had been once or twice their trysting-place, though it was by no means a safe one; and it was here she sat awaiting him now.

The noise of the stream muffled any sound of footsteps, and it was before she was aware of his approach that she looked up and saw him wading across at the top of the waterfall.
