Rosamund Elvan was what ladies call a good correspondent.

She wrote often, she wrote at length, and was satisfied with few or brief letters in reply.

Scarcely had she been a week at Cairo, when some half dozen sheets of thin paper, covered with her small swift writing, were dispatched to Bertha Cross, and, thence onwards, about once a fortnight such a letter arrived at Walham Green.

Sitting by a fire kept, for economical reasons, as low as possible, with her mother's voice sounding querulously somewhere in the house, and too often a clammy fog at the window, Bertha read of Egyptian delights and wonders, set glowingly before her in Rosamund's fluent style.

She was glad of the letters, for they manifested a true affection, and were in every way more interesting than any others that she received; but at times they made the cheerless little house seem more cheerless still, and the pang of contrast between her life and Rosamund's called at such moments for all Bertha's sense of humour to make it endurable.
Not that Miss Elvan represented herself as happy.
