prisoner.
âLearn anything?â Inspector Moon asked the detective.
âNo,â he replied. âHe wonât even tell us his name.â
âAny identification?â the inspector queried.
âNot even a driverâs license. Only thing that might help is this tattoo.â The detective pulled up the prisonerâs sleeve to show a pineapple tattoo on his left forearm.
âHmm. Itâs not much to go on,â the inspector said, âbut check the files. Anything else?â
âYes, sir. This prisoner was carrying these in his pocket, together with a ticket to Mexico.â
With a baffled look, the detective held up a pair of dollâs glass eyes! Instantly the Hardys realized they were just like the dummyâs eyes which had contained uncut diamonds!
CHAPTER VIII
Spanish Code
FRANK and Joe were excited. Here was a definite clue that tied the Eastern City holdup men to the Hugo dummy racket!
âIâd like to speak to you privately,â Frank said to the police inspector. âAnd bring the dollâs eyes along, please.â
When they were alone in a rear office, Frank declared, âThese dollâs eyes prove the man youâre holding and his gang are mixed up in the case Dadâs working on!â
âAnd what about the boxes of Variotrycin in the brief case?â Joe asked.
Inspector Moon looked thoughtfully at both boys and said that he would follow through on this angle in a few minutes, then he held up the dollâs eyes to the light.
âNo diamonds here,â he announced. âThese eyes are empty. But we still have plenty to hold Mr. Pineapple on. Maybe heâll change his mind later about talking.â
Inspector Moon asked the boys to wait while he tried to find out about the Variotrycin. He telephoned first to Watkins Pharmacy. The boys could hear both sides of the conversation.
âThat stuffâs pretty new,â Mr. Watkins told the inspector, âand very expensive. Far as I know, the Lexo Drug people that make it wonât be supplying it in quantity until they can lower the price.â
âWhere is Lexo Drug?â
Mr. Watkins said the company had a plant in Hartsburg. âIf you have a prescription, I could put in a special orderââ
âNo, thanks,â the inspector interrupted.
Hartsburg was less than a hundred miles from Bayport. Inspector Moon then placed a long-distance call to the company.
âIâd like to speak to the plant manager,â he told the switchboard girl.
A manâs gruff voice came on the line. âMcCardle speaking.â
Inspector Moon introduced himself and said, âIâm calling to find out if any shipments of Variotrycin have been stolen recently.â
The plant manager asked with a sharp note of interest, âWho did you say you were?â
âInspector Moon of the Eastern City Police Department.â
Mr. McCardle cleared his throat, then said that a special messenger carrying a consignment of their new product had been attacked and robbed late the day before.
âWhere?â
âNot far from here.â
âHave you contacted your local police?â Inspector Moon asked.
âNo. We just heard about the robbery. But Iâll do so right away,â McCardle replied.
He asked why the inspector had called him, and was told about the boxes in the brief case. âWell, we hope that you find the thief!â the manager said, then said good-by.
Inspector Moon turned to the Hardys. âHow about you fellows helping on this?â
âWe will!â the young sleuths promised.
Before leaving headquarters, Frank asked if he and his brother might borrow the doll eyes for further examination. Inspector Moon readily agreed.
The boys taxied back to the airport. Before the group took off for Bayport, Tony telephoned his father to tell what had happened. As he returned to the others, he said, âLucky break! Dad says I can have
