to the Dunn house, to find it locked up tightly. In the yard was Dave's machine, standing against the tree as he had left it.
"I guess the doctor has come and gone," said Dave, after trying all the doors. "Most likely he'll make himself scarce for a while."
"Why not interview that fellow Shime?" suggested Phil.
"I will," answered Dave, and taking the extra wheel along, the three students rode around to the Rockville livery stable and garage. Here Dave asked the proprietor about Shime.
"He has gone," said the man, sourly. "Day before yesterday he took one of my best autos for a joy ride. When he came back this morning I discharged him. He took his things and got out—and I don't know where he went to."
This was as much as the garage owner could tell, and with it Dave had to be content. He and his chums turned away; and a little later set out on the return to Oak Hall.
