received certificates attesting to the fact that they were qualified voiceprint operators.
The boysâ plane landed at the Bayport airport at noon on Saturday. Chet Morton picked them up in his jalopy. It backfired as usual, sounding like a gang war in progress. When he pulled into the Hardy driveway, the uproar brought Aunt Gertrude to the front door.
Fenton Hardyâs unmarried sister, who lived with the family, was tall and lean and had a heart as soft as a marshmallow under her decisive demeanor. She was also the best cook in Bayport, and that made her one of Chetâs favorite people.
Aunt Gertrude showed how glad she was to see the boys back safely by making a flurry of dire predictions.
âWell,â she declared as they carried their suitcases into the house, âyou survived another trip in Chetâs mechanical monster, I see. Youâll all blow up in it yet, if you donât get yourselves stabbed at that fencing school first. Or killed by robbers like those in Somerville.â
âHowâd you hear about that, Aunt Gertrude?â Frank asked.
âThe Somerville police phoned your father. He and your mother got away on their vacation, incidentally, so there will be only the three of us for lunch. Unless youâve invited guests.â
She looked pointedly at Chet, who sniffed the aroma of freshly made chili coming from the kitchen. He grinned. âIâm available if youâre looking for somebody to invite.â
âThen wash up and hurry,â Aunt Gertrude commanded. âLunch is in ten minutes.â
Shortly before three that afternoon Frank and Joe were on their way to the Russo School of Fencing.
âYou know,â Frank said, âIâve been thinking about the maestroâs problem. I wonder if we couldnât give him a hand in finding the missing piece of that saber.â
Joe grinned. âYou just want to have a little vacation on the West Coast!â
âWell, if he has any idea at all of the area where the saber was broken, it might be a good idea!â
They parked the car and went inside. Biff, Tony, and Phil came in a few moments later.
Russo beckoned to the Hardys while the others were changing to fencing suits. âIâll have to leave tomorrow for Switzerland,â he announced. âAre you boys still willing to keep the school open for me?â
âMr. Russo,â Frank began, âIâm sure the others can handle that. How would you like my brother and me to find the Adalante?â
âHow do you expect to do that?â
âWe thought if you had any clue at allââ
Russo shook his head. âI just donât know. All I can tell you is thereâs an old recluse named Miguel Jimenez who lives in the delta region of northern California. He is supposed to know the details of my grandfatherâs duel and also where the tip end of the broken sword was found.â
âHavenât you asked him about it?â Frank put in.
âHe refuses to talk to me,â the fencing master said. âI donât know why.â He scratched his head and looked thoughtfully at the boys.
âIf I paid your fare to California, perhaps you could get the old man to tell you!â
âWhatâs his address?â Joe inquired.
âI donât know. I only met him once in Stockton. He lives near there on a houseboat.â
After some discussion, the Hardys decided to leave for California on Monday.
âYouâll find that my grandfather was well known in that area,â Russo said. âThereâs a book in the Stockton Public Library about him. His name was Giovanni Russo, and he was one of the richest men in the delta at the time he died. He made his fortune from the extensive vineyard he owned there.â
âOkay, maestro,â Joe said with a grin. âYou just hired yourself a couple of detectives.â
Russo smiled. âGood luck,â he said. âAnd now
