Character guide

Frank Hardy

The steadier Hardy brother, whose cool head and stubborn resolve turn a stalled robbery case into a personal mission.

Joe Hardy

The younger Hardy, all slang and impulse, who spots the strange light in the tower and never lets his brother quit.

major

Also known as Mr. Hardy, the Hardy, Waiting Fenton Hardy

A celebrated private detective whose faith in a dying thief's confession collides with a town that has already convicted the wrong man.

The Hardys' easygoing pal, always ready to tag along on a mystery when there's fun and food to be had.

Frank's sharp-eyed girlfriend, whose loyalty and quick thinking keep the Hardy boys grounded between clues.

Red Jackley

supporting

Also known as Jackley, Red, XIV Red Jackley

A dying red-haired thief whose last confession sends the Hardy boys hunting for loot no one can find.

Ezra Collig

supporting

Also known as Chief Collig, Collig, IV The Holdup Chief Ezra Collig

Collig runs the local force alongside the fumbling Detective Smuff, and he treats the Tower Mansion robbery as much as a turf war with Fenton Hardy as a case to solve. He complains loudly that Hardy won't cooperate, though his real motive may be the thousand-dollar reward, and he threatens to grill the wounded Red Jackley at the hospital before the doctor will allow it. His obstruction and bluster push the Hardy boys to work the mystery on their own, making him a recurring wall they must outmaneuver.

Hurd Applegate

supporting

Also known as Mr. Applegate, Applegate, old Applegate

Applegate is a stamp-collecting eccentric who hires Fenton Hardy after a thief cracks his tower safe, then swings between smug disbelief and eager cooperation as the boys press their theories. Quick-tempered and easily swayed, he first scoffs at the search of the old tower, then insists on helping ransack the new one, and he's quick to blame his fired handyman Robinson. His reward money and shifting moods keep the case in play and give the Hardy boys their central client.

Detective Smuff

supporting

Also known as Smuff, the loyal Smuff

Smuff trails Chief Collig through Bayport's investigation, gravely taking notes and grandly accusing Fenton Hardy of obstructing justice when Hardy refuses to share his leads. He and Collig scheme to interrogate the dying Red Jackley at the hospital, a plan the Hardy boys scramble to foil. His comic ineptitude sharpens the contrast with the boys' real detective work and raises the stakes of the race to the hospital.

Mr. Robinson

supporting

Also known as Robinson, rascal Robinson

Robinson was fired from Tower Mansion and, in the eyes of Hurd Applegate, remains the likeliest thief, since he can't account for the cash he suddenly had. The boys find it hard to believe him guilty, but his shadow hangs over every theory about where the loot went. His ambiguous guilt keeps the mystery's central question open and tests the Hardys' instinct for reading people.

Perry Robinson

supporting

Also known as Perry

Perry, nicknamed Slim, brings Fenton Hardy a crucial detail: a strange man lurking near Tower Mansion two nights before the robbery. With his father jailed on thin evidence, Perry is desperate and eager to help, and his eyewitness account links the burglar to the red-wigged fugitive the boys are chasing. His stake in the case gives the mystery a human cost and motivates the Hardys to push harder.

Slim Robinson

minor

Also known as Slim, Slim Robinson

Another son of Mr. Robinson, a chum of the Hardy boys.

Adelia Applegate

supporting

Also known as Adelia, XXIII Adelia Applegate

Adelia Applegate greets the Hardy boys with suspicion and a sniff, dismissing detectives as nosey and insisting the jewels will never be found. Dressed in outdated, garish finery and quick to needle her brother, she clings to the theory that Robinson is the thief and scoffs at every new lead. Her skepticism makes her a comic foil and a stubborn obstacle the boys must win over as they search the towers.
