Mollie blushed, and the boys giggled. "Look here," said Dick, "if we stand here till midnight discussing Major Campbell's age we won't get home to tea, and then Aunt Mary will send out a search party, and we'll look pretty asinine. Long John's getting baity, he'll bolt in a minute. Take the reins, Mollie. Don't eat all the strawberries, and tell Aunt Mary that cherry jam is my fancy. Come on, Young Outram." Major Campbell saw the boys start before taking the reins from Mollie. Long John gave his head an impatient toss, and set off with the determination that he would not stop again for anybody till he was in sight of his stable. A hundred thoughts chased each other through Mollie's mind. Of course this could not possibly be _that_ Hugh Campbell. It would be altogether _too_ queer. And yet--after all, nothing could be much queerer than the experience they had already had. Putting one thing and another together it did seem to be more than a coincidence that a Hugh Campbell should be on his way to see someone who had a green diamond set in a ring given to her "long, long ago". She stole a look at her companion as he sat opposite her, his eyes fixed on the road ahead and his thoughts obviously elsewhere. Hugh the inventor had not passed even thirteen years without gathering various little mementoes of his inventions in the shape of scars here and there, and these had not escaped the sharp observation of Mollie, the Girl Guide. There had been a tiny gap in his left eyebrow, the result of inventing a new pattern of firework--a crooked little finger on his left hand--a funny star-shaped mark on his right jaw. Some of these and other remembered marks might have been obliterated by time, but if even one remained she would recognize it. He had removed his hat and disclosed a head of closely cropped grey hair, which made him look older. Yes--there was the gap in his eyebrow _and_ the crooked finger. Mollie felt certain that this was indeed the inventor. "Have you ever been in Dublin?" she asked abruptly, forgetting for the moment that asking questions was forbidden. "In Dublin?" echoed Major Campbell, bringing his eyes and his thoughts from the winding road and concentrating both upon Mollie. "Are you a thought-reader, Miss Mollie? For I was thinking of Dublin at that very moment. Yes, I have been there. Indeed, it was there that I first met Miss Gordon, at a ball at Dublin Castle. I was visiting some people she knew, and later on she joined us. My sisters were over here at that time too. Has Miss Gordon ever mentioned the O'Rourkes to you?" "Yes," said Mollie, feeling absolutely giddy with excitement, "that is, no--not exactly----" she felt very confused--"I mean--was there a Desmond O'Rourke?"
