the basement fell shut all by itself,â she explained. âI couldnât get it open, so I went looking for help. I was going to ask Mr. Wester to let you out, but heâs on the phone.â
âWe found another exit,â Frank informed her, then looked at her sharply. âDo the initials I.N. mean anything to you, Mrs. Summers?â
The housekeeper seemed startled, but shook her head. âNo one here has those initials,â she insisted.
âMay we see Mr. Wester now?â Joe asked.
âCertainly.â Mrs. Summers let them in, and the young detectives joined the art collector in his study. Wester hung up the phone as they walked through the door. He was taken aback when he heard about the secret passage in the basement. âI never knew it was there!â he declared. âBut then, the house was built over a hundred years ago.â
Frank had an idea. âMr. Wester, if your secretary had anything to do with the theft of the painting, perhaps he stole other things, too. Have you noticed anything else missing?â
Wester shook his head but told Mrs. Summers to check. She came back shortly afterward, looking upset. âI didnât notice before,â she said, âbut the big silver pitchers have been taken out of the sideboard. Also the tall golden candlesticks.â
âSomeone, perhaps Morphy, has been robbing you blind,â Joe commented.
âI just wonder why he didnât take more of the valuable paintings,â Frank mused.
âHe probably figured it would be too obvious,â Joe reasoned.
Mrs. Summers nodded. âThe pitchers and candlesticks were not openly displayed,â she said. âI wouldnât have discovered that they were gone unless Iâd checked.â
âDid you find a clue while you were looking through the house?â Wester asked the boys.
âJust this,â Frank said, showing him the jackknife.
The art collector did not recognize it, nor did he know the initials I.N. The Hardys then inspected the area above the fireplace where the BolÃvar portrait had hung. A spot on the wall caught Frankâs eye. He scrutinized it closely. âThis is a pretty clear fingerprint,â he declared. âJoe, do you want to get our kit from the trunk of the car?â
âIâll be right back,â Joe said. He returned with a small box and sprinkled some powder over the spot. Then he photographed it with a small camera before lifting the print with a piece of special tape.
He turned to Wester. âIf itâs okay with you, Iâll take another print from Morphyâs room and weâll see if they match.â
Wester told him to go ahead, and Joe left the study. Frank looked thoughtfully at the empty wall over the fireplace. âI wonder why whoever mon keyed with the picture didnât wear gloves.â
Wester glowered at him. âMaybe you know as well as I do that the picture wire was twisted around the hook. The thief had to use his fingers to loosen it.â
They discussed the mystery until Joe returned.
âI took a perfect print from the mirror Morphy used for shaving,â the younger Hardy boy revealed. âNow we can have Chief Collig check both of them at police headquarters. Mr. Wester, weâll get back to you when we find out if they match. If they donât, the police might be able to figure out whose they are from their records.â
Wester nodded. âWhile youâre there, tell him my house has been robbed.â
âWeâll be glad to make the report for you,â Frank assured him.
The art collector glared at him. âAnd donât forget to mention to the chief that it seems the main suspects are Frank and Joe Hardy!â

A Cry for Help
Frank and Joe stared at the art collector. Apparently he still believed they were guilty!
âWeâll have to find Mark Morphy to clear ourselves,â Frank said slowly. âWhat does he look like,
