“Spooks,” echoed Ben, edging a trifle away from the open trap door.

“Call it that,” said Mr. Edson, with a quiet smile. “Perhaps I had better say—mysterious happenings.”

“What may they be, Mr. Edson?” inquired Ben, always interested in any sensational disclosures.

“Well, first—let me see,” and the speaker reached over for a slip of documents held with others in a paper clip on the table; “yes, here it is—‘Donner.’”

“Who’s he?” inquired Tom, puzzled.

“Say rather what is he?” corrected Mr. Edson. “Frankly, I don’t know.”

“It’s a name,” observed Ben; “a man’s name, isn’t it?”

“I don’t know that,” responded Mr. Edson.

“Neither do the other fellows on the circuit. Perhaps I’d better explain, though, so when this Donner comes along you will be prepared for him.”

“Yes, you have excited our curiosity and we’ll be on the lookout,” said Tom.
