Born with the proverbial silver spoon in her mouth, reared in the even more proverbial lap of luxury, the lady didn't know what it meant to make ends meet. Her ends had always luxuriously overlapped. But the time came when the lady had to choose between dread poverty and a wedding ceremony with a rich invalid whose only knowledge of youth was a distant memory. She was led to the altar where she mouthed. "till death do us part" farce, and went to live out her lie with a man whose wealth was the only thing about him she loved. To live with a man she didn't love would, under ordinary circumstances, have been difficult enough; it was the natural aversion of Youth for Age, but when, added to this, she found she had fallen desperately in love with her husband's young medical attendant, her life perforce became a torturous labyrinth of lies and fears of apprehension. It is at this point that "The Love Liar" makes its greatest appeal to your insistent demand for unflinching realism in the place of the usual lollipop romanticism.
