Mrs. Hardy hurried forward.

"Get me a glass of water, Frank," she said quickly. "She has fainted."

CHAPTER IV

Concerning Todham Todd

It was quite evident that Miss Todd was in no condition to go to any of the city hotels. She needed rest and quiet more than anything else, and when she had been revived a few minutes later, Mrs. Hardy insisted that she remain in the Hardy home for a few days as a guest. Her sympathy had gone out to the distracted woman, and although at first Evangeline Todd would not consider the proposal, being afraid of imposing on their hospitality, Mr. Hardy insisted that she remain.

"Your story interests me very much," he said. "I'll be very glad to take the case, on one condition."

"What condition is that?"

"On condition that you accept our invitation to stay here for a while until you are feeling better."

So Evangeline Todd was prevailed upon to stay and Fenton Hardy at once prepared to take up the trail of the missing professor. He had no important cases in hand at the time, so he was able to spare a few days for preliminary investigation work and he decided that his best plan was to go directly to the college town where the Todds had their home.

"Sometimes a professional, and a stranger, can pick up clues that wouldn't fall in the way of a police detective who is known in the town," he said. "I'll run up there and see what I can discover."
