There was an exquisite lightness of raillery in the suggestion which absolutely barred offence, and there was kindness in the keen old eyes. Nevertheless, Marmaduke was uncomfortably aware that they took in his sudden flush. She gave him no time for interruption, however, and went on airily--

"For all I know the heir may already be in existence!" Here Marmaduke asserted himself with great dignity. "My dear madam, if I had any children I should acknowledge them!"

Louisa Lady Broadway smiled gently. She had gained one piece of knowledge, anyhow. The obstruction, if there was one, was a childless wife.

"I am glad to hear it, my dear, but I knew you had a good heart, or I wouldn't have risked speaking to you. I wouldn't do as much for one in a thousand. Now, my dear, I am nearly eighty years old, and I understand things as perhaps few women do understand them. I don't expect many men have lived to be your age without forming ties of some kind, especially if they live in Scotland, Marmaduke"--the thrust went home again, she thought--"but money does a lot, especially when there are no children. A good round annuity means much when a man is not well off, as you are, and has probably to wait for many years ere he falls into money--as you have, for Pitt is the heir, of course. But your father would find the cash----"

"If he would find the money to pay for my colonelcy," burst in Marmaduke, "it would be better than setting people to find out mare's nests! I don't mean to be rude, Lady Broadway; you are very kind, but I really can't discuss----"

"I think you can," interrupted Louisa Broadway in her turn, "especially if it is not a question of mere money, and money is, I believe, a very small matter to some people--to you, for instance, Marmaduke! You never think of it, do you, so long as you've got it?--ha, ha! But there are other considerations. To begin with, I believe that when there are no children a marriage should automatically become null and void. And apart from that I don't believe that any woman who really loves a man would ever stand in his light or prevent him from doing his duty. I am sure if I had had no children, and Broadway----" The illustration, however, was beyond even her powers of fiction, and the opening of the door brought relief. "Oh, here is the young lady! Amabel, let me introduce Major Marmaduke Muir. Major Muir, Lady Amabel Sibthorpe. I expect you are kindred spirits, as you are both such outdoor people."

The girl, who had rushed in somewhat unceremoniously, looked up frankly into Marmaduke's blue eyes. There was undisguised admiration in her glance.

"Oh, yes," she said, "I've always wanted to know Major Muir since I saw him punish a horrid little boy in the park for bullying his dog!"

Marmaduke, as he made his bow, felt that the clever old lady with the painted face was very clever indeed. She had gauged her man completely. Most people on the task would have supplied him with a befrilled fashionable beauty; the sort of woman with whom he flirted, who amused him, attracted him, tempted him. But this joyous, buoyant girl, with good-breeding in every line and feature----

No, Louisa Lady Broadway had made a mistake; she had reminded him of Marrion Paul.
