“The fellow who follows Merriwell wants to take out a life insurance,” he hoarsely whispered.

Then, with some difficulty, he let himself down and dropped heavily to the ground.

When all were over, Frank led them from the yard, and soon they were on the street.

“Griswold,” said Frank, “make a hustle for a cab, and bring it to the corner nearest Mrs. Henderson’s. If you are not lively, we’ll be there ahead of you.”

“O. K.,” said Danny. “I won’t be more than a year.”

Away he scudded.

“Now,” said Frank, “if Rudge is where Blossom said, we’ll have him inside of fifteen minutes. Come on.”

They followed him, and soon he led them round into York Street.

Opposite Mrs. Henderson’s house was a tree with wide-spreading branches. Beneath that tree was a deep shadow, where the electric lights did not reach.

The boys took the opposite side of the street and walked along by twos as if they were on their way to their rooms and happened to come that way. From their manner no one would have suspected they had lately come from Mrs. Henderson’s, or that they were looking for the spying proctor.
