He leaned forward.
"But in you I don't mind it."
"I don't say I acknowledge it. But why should you mind it in any one?"
Nigel quoted some words of Mrs. Chepstow, but Isaacson did not know he quoted.
"Hasn't the brain a tendency to overshadow, to brow-beat the heart?" he said. "Isn't it often arrogant in its strength?"
"One must let both have an innings," said Isaacson, smiling at the slang which suited him so little and suited Nigel so well.
"Yes, and I believe you do. That's why--but to go on with what we were saying. You've got a long sight into things. Now, living generally, as you do, here in London, don't you think that men and women living in crowds often get off the line of truth and kindness? Don't you think that being all together, backed up, as it were, by each other--as a soldier is by his regiment when going into battle--they often become hard, brutal, almost get the blood-lust into them at times?"
Isaacson did not reply for a moment.
"Perhaps sometimes they do," he answered at last.
"And don't you think they require sacrifices?"
"Do you mean human sacrifices?"
"Yes."
"Perhaps--sometimes."
"Why have you never been to call on Mrs. Chepstow?"
Again the sallow fingers began to play with the book-covers, passing from one to another, but always slowly and gently.
"I haven't much time for seeing any one, except my patients, and the people I meet in society."
"And of course you never meet Mrs. Chepstow in society."
"Well--no, one doesn't."
"She would have liked a visit from you, and she's very much alone."
"Is she?"
"Are you stopping on much longer in London?"
"Till the twelfth or fifteenth of August."
"She is stopping on, too."
"Mrs. Chepstow! In the dog-days!"
"She doesn't seem to have anywhere special to go to."
"Oh!"
Isaacson opened a book, and laid his hand upon a page. It happened to be a book on poisons and their treatment. He smoothed the page down mechanically and kept his hand there.
"I say, Isaacson, you couldn't have the blood-lust?"
"I hope not. I think not."
"I believe you hate it as I do, hate and loathe it with all your soul. But I've always felt that you think for yourself, and don't care a rap what the world is thinking. I've looked in to-night to say good-bye, and to ask you, if you can get the time, just to give an eye to--to Mrs. Chepstow now and again. I know she would value a visit from you, and she really is infernally lonely. If you go, she won't bore you. She's a clever woman, and cares for things you care for. Will you look in on her now and then?"
