and returned a few moments later with his handkerchief soaked with cold brine. After the boys had applied it to their fatherâs forehead and chafed his wrists, Mr. Hardy began to revive.
âJoeâFrankâHi, Chet.â The detective gave them a rueful smile, then slowly raised himself to a sitting position.
âWhat happened, Dad?â asked Frank.
Mr. Hardy frowned and rubbed his hand over his eyes. âLet me seeâOh, yes, those red-light signals from the tower here.â
âWe saw âem too!â declared Chet.
âSomebody knocked out Dad!â Frank said worriedly
âSo did Iâfrom my campsite on the other side of the island,â Mr. Hardy went on slowly. âI came over to investigate, entered this doorway, andâwham!â
âHow do you feel now?â Joe inquired.
âNot too bad, except for this throbbing lump. Lucky for me I have a thick skull.â
The boys helped Fenton Hardy to his feet, then began a search of the tower. They checked every floor, up to the lantern room, but the assailant had vanished. Warily, the detective and the three youths tramped back across the island to his camp on the cove.
The fire had long since burned down to glowing embers. After it had been replenished with drift-wood and dry brush, Frank showed his father the cablegram from Egypt and the map which had been sent through the mail by âR. Rogers.â
âWhatâs this Pharaohâs head youâre supposed to beware of, Dad?â asked Joe.
âItâs a solid gold bust of the Egyptian Pharaoh, or Emperor, Rhamaton IVâvalued at one million dollars.â
Chet let out an awed whistle. âA million bucks! Wow! Where is this head, Mr. Hardy?â
âA good question, Chet,â the detective replied wryly. âIâd better start at the beginning. About two weeks ago, a freighter named the Katawa sank off the coast. Maybe you fellows recall hearing about it in the news. Several of the crew, including the purser, drowned.â
âIt was rammed in a fog by some cruise liner, wasnât it?â said Frank.
âThatâs rightâby the Carona. Well, the spot where the freighter went down is just a couple of miles north of Whalebone Island.â
Mr. Hardy explained that the Katawa had been carrying not only cargo, but also a dozen passengersâone of them a foreign art dealer named Zufar, who had boarded the ship at Beirut in the Middle East.
âZufar was bringing the golden Pharaohâs head with him,â the detective continued, âto sell to a customer in New York. And the head was allegedly in the shipâs strong room when the Katawa sank. Zufar has lodged a claim with Transmarine Underwriters, the lineâs insurance company, for a million dollars.â
âThe news stories on the sinking never mentioned the Pharaohâs head, did they?â Joe asked.
âNo. As a security precaution, Zufar had purposely avoided any publicity about the treasure, and since the sinking, the line has also tried to keep the matter out of the news for the same reason.â
âYou said the head was allegedly in the shipâs strong room,â said Frank. âIs there some doubt about it?â
âThatâs where the mystery comes in, and thatâs why Transmarine has engaged me to investigate the case,â Mr. Hardy replied. âTheyâve been tipped off that a gold head of Rhamaton IV is secretly being offered for sale.â
âWas the tip on the level?â Joe asked.
âSo far we donât know. Iâve been checking it out, but may not know the answer until divers get at the Katawaâs strong room. Meantime, the tip brings up a number of interesting possibilities.â
âRight,â Frank said. âThe head being offered for sale might be a fake. Either that, or the one that went down with the Katawa was a phony.â
Mr. Hardy smiled at the rapid-fire
