Why it matters

The obvious suspect has both a public grievance and a strong alibi, forcing Jones to re-examine a conviction from his early career.

Grady Felton served a prison sentence for killing Daniel Denning while insisting that he was innocent. On release he returns to Binwell, where the people he blamed for his conviction—including Ben Jones, then a constable—are named on a death list and start becoming murder victims.

Grady's alibis prevent Barnaby from accepting the obvious solution, and an arson attack against him further complicates the pattern. Jones must revisit the original investigation while new deaths ask whether the list is a plan, a frame or an attempt to correct an older injustice.

Who was the killer in Murder of Innocence? (spoiler)

Grady Felton

Felton killed Giles Harrison, Kyle Gideon, Caroline Garrett and his disguised former cellmate Keith Mulory, then tried to kill Jones and Ted Denning. Deirdre Denning accidentally caused Daniel's death during a sibling argument; her silence led to Felton's wrongful conviction, but the episode does not recast that accident as one of his murders.

Verified motive

Grady took revenge on the people he blamed for scapegoating him and stealing eighteen years of his life, culminating in attacks on Jones and Ted Denning. He killed accomplice Keith Mulory after the failed cottage sale made Mulory a threat to the identity-swap scheme that had freed Grady to act.

Verified important clue

Archive case 91 · checked 17 September 2026The fingerprint-and-DNA mismatch on the supposed Grady Felton

The dead man's digitised fingerprints match Grady while his DNA identifies cellmate Keith Mulory; recent scars, a tattoo and eye surgery confirm the substitution, overturning the CCTV alibi and proving that the real Grady has been free to carry out the revenge killings.

Verified decisive clue

Archive case 91 · checked 25 September 2026The fingerprint and DNA mismatch on the supposed Grady Felton

The dead man's digitised prints match Grady's record, but his DNA identifies Keith Mulory. The original paper prints do not match him, and recent scars, a tattoo and eye surgery support the impersonation. The mismatch breaks the apparent bus CCTV alibi: the real Grady has been free to commit the revenge murders while his former cellmate posed as him.

Verified death and discovery order

  5. death
