"I heard Lady Arabella's invitation to you to come to Diana's Grove." "Well, what on earth has that got to do with it?" "Nothing directly that I know of. But we shall see." Adam waited, and the old man went on: "Have you by any chance heard the other name which was given long ago to that place." "No, sir." "It was called--Look here, this subject wants a lot of talking over. Suppose we wait till we are alone and have lots of time before us." "All right, sir." Adam was filled with curiosity, but he thought it better not to hurry matters. All would come in good time. Then the three men returned home, leaving Mr. Caswall to spend the night in Liverpool. The following day the Lesser Hill party set out for Castra Regis, and for the time Adam thought no more of Diana's Grove or of what mysteries it had contained--or might still contain. The guests were crowding in, and special places were marked for important people. Adam, seeing so many persons of varied degree, looked round for Lady Arabella, but could not locate her. It was only when he saw the old- fashioned travelling carriage approach and heard the sound of cheering which went with it, that he realised that Edgar Caswall had arrived. Then, on looking more closely, he saw that Lady Arabella, dressed as he had seen her last, was seated beside him. When the carriage drew up at the great flight of steps, the host jumped down and gave her his hand. It was evident to all that she was the chief guest at the festivities. It was not long before the seats on the dais were filled, while the tenants and guests of lesser importance had occupied all the coigns of vantage not reserved. The order of the day had been carefully arranged by a committee. There were some speeches, happily neither many nor long; and then festivities were suspended till the time for feasting arrived. In the interval Caswall walked among his guests, speaking to all in a friendly manner and expressing a general welcome. The other guests came down from the dais and followed his example, so there was unceremonious meeting and greeting between gentle and simple.
