got down there the captain saw something he wasnât supposed to see.â
âThen Donner, or somebody, had to get him out of the way because he knew too much!â Joe finished grimly. âRemember the blood we found on the leaves?â
Absorbed in this new possibility, Frank, Joe, and Chet failed to notice that Simon had been making his way quietly toward the back door. In a moment the tall boy had slipped out into the night!
âHey!â called Chet. âStop him!â
âNo, let him go,â said Frank Hardy calmly. âSimonâs on our side, all right.â
âI just wish we could do something to help him,â Joe put in. âWith his talent for drawing he might make out very well in spite of his handicap. He should go to a special art school.â
Frank agreed, then said reflectively, âI canât seem to get Colonel Thunder out of my mind, and his resemblance to Donner. Also, I wonder if it could be more than coincidence that the German word for thunder is donner. What do you say we find the carnival, and talk to the colonel? He just might be a relative of Donner.â
âSuppose we drive to Forestburg in the morning,â Joe suggested. âMaybe we can learn something there about the Donner family, and find out where the carnival is. Besides, itâs about time we called Mother to see how things are in Bayport!â
Morning dawned bright and fresh after the rain, everything seemed greener than before, and the boysâ spirits rose. Frank and Joe emerged from the cabin, followed by Chet, who cradled Mystery in his arms. But suddenly Frank stopped and frowned.
âOhâoh! So much excitement last night we forgot to put up the convertible top before the storm. Now look!â
Sure enough, there were puddles on the floor of the Hardysâ car, and the seats, though protected by covers, were wet. The boys mopped up the water.
âLetâs take Captain Maguireâs car,â said Joe. âIf the captainâs enemies see it, they may think he escaped, and that will bring them into the open.â
The three set off with Joe at the wheel, Frank beside him, and Mystery and Chet in the rear.
Apparently the back seat was comfortable, for by the time the car entered Forestburg, both Chet Morton and the beagle were fast asleep.
âLet âem alone.â Frank laughed. âLast night was too exciting, I guess. You and I can do the detective work, Joe.â
The two boys walked a block to the courthouse. Because it was only eight oâclock, the streets had little traffic. Frank and Joe, alert with curiosity, looked around. Many stores had offices above. In one upstairs window, which Joe pointed out, was a small sign:
WYCKOFF WEBBER
Attorney-at-Law
The brothers crossed the street to the courthouse. No one was at work yet.
âWell, letâs try the stores,â suggested Joe. âSomebody here must know the Donners.â
During the next hour the two young detectives went from shop to shop asking questions about the Donner family. Although one or two clerks or storekeepers admitted the name âsounded familiar,â nobody could give any definite information.
âIâll tell you what weâre up against,â said the exasperated Joe. âSome of these people are new in town, and they just donât know the Donners. The others know them, but wonât talk to us. Weâre outsiders, and they think weâre prying into local affairs that arenât any of our business!â
âMaybe so,â agreed Frank. âBut thereâs one shop I have to visit fast!â He indicated a tailorâs establishment at the end of the block.
âWhat for?â demanded his brother, puzzled.
âJust discovered,â muttered Frank, âI have a hole in my slacksâmust have caught them on the rocks last night!â
A little man with shining bald head and thin black hair at the temples greeted
