"It must have been something awful to hear him," shuddered Bob.

"I wonder what they did with the body?" queried George.

"Buried it or burned it, I suppose. I guess when the detectives get hold of these fellows they'll be able to get out of them what they did with the body."

"Well, what are we going to do about it?" asked Frank.

"It seems to me that we ought to tell the police about it right away," replied Sammy.

"But how can we do that?" asked Bob.

"Oh, I don't know exactly," confessed Sammy, vaguely. "I suppose, though, that one of us could get off at a station and send a telegram to the police of some town ahead of us."

"We wouldn't need to get off the train for that," said George. "There's a telegraph office in one of the cars ahead. But I think it would be better to tell the whole thing to the conductor. He'll know what's the best thing to do."

"But don't tell him just yet," put in Frank. "Perhaps the men will give themselves away more yet if we wait a little while. We'll all keep our ears open to-night and see what we can find out."

Further conversation stopped just then, for the two men came back from the dining car and settled into their seats. They seemed in especially good humor after their dinner. One of them even turned part way round in his seat and tried to get into conversation with the boys.
