In short, he was treated with such wholesome and charming hospitality as to set him to wondering, after it was all over and he had gone to bed, whether he had not missed something in his solitary life, brought up without the love of father, mother, sister or brother, in a home where noise and cheerfulness were outlawed.

He was up bright and early the next day, and he and the banker went to see Mr. Warren, who was let into the secret, and the reward of five hundred dollars was, through him, placed to the credit of the boys. Then there was the aged aunt of Mrs. Carlin to call upon, and the time passed quickly till it was time for the afternoon train.

It was about two o’clock in the afternoon when Henry Burns boarded the train in the company of Miles Burton.

“Now,” said the detective, as the train rattled noisily on its way, “I have been in Mayville and know several parties there, but the island is new to me. However, you can explain it to me from this map,” and Mr. Burton unrolled a map of the bay and island from his pocket. “I shall pick up three of my men, whom I have ordered to meet us, in Mayville. One of them came all the way down from New York with me to help me work up this case. It is my opinion he traced this man Craigie to Mayville and lost track of him there. The man must have vanished, as he has done so often before.

“We will go over to the island to-night in a launch. Then we shall need some one to guide us to what you call the haunted house.”

“I will meet you in the road by Captain Hervey’s house, right at the very head of the island,” said Henry Burns. “It is the first house you come to on landing at the outermost point. You cannot miss it.”

“But how will you get there? It is a long trip up the island.”

“I will come on my bicycle.”

“Capital! You will go direct to the island, then, by the night boat, arriving there, you say, at six o’clock. You will see just how the land lies, so you can tell us, when we meet again. And you will instruct your friends to keep close to Craigie, so he won’t be over there at the house to meet us on our arrival. We want to do the welcoming for him, and not have him do it for us. Two of the men I shall bring are somewhat familiar with the island and know one or two parties there; though I am not sure they know where the haunted house is.

“One of you boys must have a boat always in readiness somewhere up the cove, on which you say this house fronts, so that, the minute this man meets his confederates aboard the yacht, one of you can slip across the cove and let us know of it, in case we have missed them.
