‘That word “stumbled,” my dear,’ Longstreet told her with great dignity, ’is extremely offensive to me at a moment like this.  It is a word which you have employed in this same connexion before to-day, yet it is one to which I have always objected.  In that sure progress which marks the path a scientific brain has followed, there are no chance steps.  Surely my own daughter, after the evidence I have already given——­’

‘That isn’t the point,’ said Helen hurriedly.  ’The only thing that counts now is that you mustn’t go shouting of it from the housetops.’

‘Am I shouting, my dear?  Am I seeking the housetops?’ His dignity swelled.  Also, it was clearly read in his unusually mild eyes that Helen, in her excitement with her ill-chosen words, had hurt him.  Sanchia Murray, for one, who was older and of wider worldly experience than Longstreet’s other companions of the moment, and who surely knew as much of human nature, saw something else in his clouded look.  It was an incipient but fast-growing stubbornness.  Therefore Sanchia closed her lips and watched keenly for developments.

‘There’s a good old pops,’ Helen cajoled.  She slipped between him and Sanchia, sending Howard a meaning look.  She made use of certain of the widow’s own sort of weapon, putting her two round arms about her father’s neck.  Before he quite understood what was happening to him, she had managed to get him through the door which led to her room at the rear, and to close the door after them and set her back to it.  Forthwith her cajolery was done with, and taking him by the two shoulders Helen looked severely into his wondering eyes.

She began speaking to him swiftly, but her voice lowered.  She had marked how Sanchia had sought to follow, how Howard had put his hand on her arm and Sanchia had shown her teeth.  The woman was in fighting mood, and Helen from the beginning was a little afraid of what she might succeed in doing.

‘Papa,’ she said, ’anyone can see what that woman is after.  She robbed you once, and anyone can see that too.  You are a dear old innocent thing and she is artful and deceitful.  You are not safe for a minute in her hands; you must stay right in here until Mr. Howard and I can send her away.’

She felt Longstreet’s body stiffen under her hands.

’If you mean, my dear, that your father is a mere child; that he cannot be trusted to know what is best; that you, a chit of a youngster, know more of human nature than does he, a man of years and experience; that——­’

‘Oh, dear!’ cried Helen.  ’You are wonderful, pops, in your way.  You are the best papa in the world.  But, after all, you are just a baby in the claws—­or hands of a designing creature like that hideous Sanchia.  And——­’

‘And, my dear,’ maintained Longstreet belligerently, the stubbornness now rampant in his soul, ’you are mistaken, that is all.  You and I disagree upon one point; you condemn Mrs. Murray outright, because of certain purely circumstantial evidence against her.  That is the way of hot-headed youth.  I, being mature, even-minded and clear-eyed, maintain that one accused must be given every opportunity to prove himself innocent.  When you say that Mrs. Murray is untrustworthy——­’
