"May I tread," said he, "on the most delicate of grounds?"

"It all depends," said I, "on how delicately you do it."

He made a courteous movement of his hand and smiled. "I'll do my best. I take it that you're very fully admitted into Andrew Lackaday's confidence."

"To a great extent," I admitted.

"And--forgive me if I am impertinent--you have also that of the lady whom we have just left?"

"Really, my dear Bakkus----" I began.

"It is indeed a matter of some importance," he interposed quickly. "It concerns Madame Patou--Elodie. Rightly or wrongly, she received a certain impression from your charming luncheon party of yesterday. Andrew, as you are aware, is not the man with whom a woman can easily make a scene. There was no scene. A hint. With that rat-trap air of finality with which I am, for my many failings, much more familiar than yourself, he said: 'We will cancel our engagement and go to Vichy.' This morning, as I wrote, I was called to Clermont-Ferrand. Madame Patou, you understand, has the temperament of the South. Its generosity is apt to step across the boundaries of exaggeration. In my capacity of friend of the family, I had a long interview with her. You have doubtless seen many such on the stage. I must say that Andrew, to whom the whole affair appeared exceedingly distasteful, had announced his intention of obeying the rules of common good manners and leaving his farewell card on Lady Auriol. Towards the end of our talk it entered the head of Madame Patou that she would do the same. I pointed out the anomaly of the interval between the two visits. But the head of a Marseillaise is an obstinate one. She dressed, put on her best hat--there is much that is symbolical in a woman's best hat, as doubtless a man of the world like yourself has observed--and took the tram with me to Royat. We alighted at the further entrance to the park, and came plump upon a leave-taking between Lackaday and Lady Auriol. You know there is a turn--some masking shrubs--we couldn't help seeing through them. She was for rushing forward. I restrained her. A second afterwards, Andrew ran into us. For me, at any rate, it was a most unhappy situation. If he had fallen into a rage, like ninety-nine men out of a hundred, and accused us of spying, I should have known how to reply. But that's where you can never get hold of Andrew Lackaday. He scorns such things. He said in his ramrod fashion: 'It's good of you to come to meet me, Elodie. I was kept longer than I anticipated.' He stopped the Clermont-Ferrand tram, nodded to me, and, with his hand under Elodie's elbow, helped her in."

"May I ask why you tell me all this?" I asked.

"Certainly," said he, and his dark eyes glittered in the moonlight. "I give the information for what it may be worth to you as a friend, perhaps as adviser, of both parties."

"You are assuming, Mr. Bakkus," I answered rather stiffly, "that Madame Patou's unfortunate impressions are in some way justified."
