She's--she's very good--in her way

"She's--she's very good--in her way. She's had a difficult life...."
"You can't leave a man about for a moment," Lady Marayne reflected. "Poff, I wish you'd fetch me a glass of water."
When he returned she was looking very fixedly into the fire. "Put it down," she said, "anywhere. Poff! is this Mrs. Helter-Skelter a discreet sort of woman? Do you like her?" She asked a few additional particulars and Benham made his grudging admission of facts. "What I still don't understand, Poff, is why you have been away."
"I went away," said Benham, "because I want to clear things up."
"But why? Is there some one else?"
"No."
"You went alone? All the time?"
"I've told you I went alone. Do you think I tell you lies, mother?"
"Everybody tells lies somehow," said Lady Marayne. "Easy lies or stiff ones. Don't FLOURISH, Poff. Don't start saying things like a moral windmill in a whirlwind. It's all a muddle. I suppose every one in London is getting in or out of these entanglements--or something of the sort. And this seems a comparatively slight one. I wish it hadn't happened. They do happen."
An expression of perplexity came into her face. She looked at him. "Why do you want to throw her over?"
"I WANT to throw her over," said Benham.
He stood up and went to the hearthrug, and his mother reflected that this was exactly what all men did at just this phase of a discussion. Then things ceased to be sensible.
From overhead he said to her: "I want to get away from this complication, this servitude. I want to do some--some work. I want to get my mind clear and my hands clear. I want to study government and the big business of the world."
"And she's in the way?"
He assented.
"You men!" said Lady Marayne after a little pause. "What queer beasts you are! Here is a woman who is kind to you. She's fond of you. I could tell she's fond of you directly I heard her. And you amuse yourself with her. And then it's Gobble, Gobble, Gobble, Great Work, Hands Clear, Big Business of the World. Why couldn't you think of that before, Poff? Why did you begin with her?"
"It was unexpected...."
"STUFF!" said Lady Marayne for a second time. "Well," she said, "well. Your Mrs. Fly-by-Night,--oh it doesn't matter!--whatever she calls herself, must look after herself. I can't do anything for her. I'm not supposed even to know about her. I daresay she'll find her consolations. I suppose you want to go out of London and get away from it all. I can help you there, perhaps. I'm tired of London too. It's been a tiresome season. Oh! tiresome and disappointing! I want to go over to Ireland and travel about a little. The Pothercareys want us to come. They've asked us twice...."
Benham braced himself to face fresh difficulties. It was amazing how different the world could look from his mother's little parlour and from the crest of the North Downs.
"But I want to start round the world," he cried with a note of acute distress. "I want to go to Egypt and India and see what is happening in the East, all this wonderful waking up of the East, I know nothing of the way the world is going--..."
