Orson wells tells how a regular car tire ended up in Scotland Yard’s museum of murder.

A car theft goes off without a hitch until the two speeding car thieves are stopped in a routine traffic check. Suspicions are raised when the crooks have no ID. Guns blaze. A cop lies dead in the road, and the thieves reach their hideout.

The investigation begins with clues at the crime scene. A pencil in the cop’s hand. Tire tread marks match ones used on only one make of car. An abandoned stolen Evans is found. Matched with a recent theft, and connected with the crime, Scotland Yard digs its teeth into solving the murder. With no witnesses, is there any chance of locating the driver of the stolen car?

The tires of the Evans have been stripped, and local garage owners are checked out. When one shop has a set of the rare tires, red flags are raised and inspection of business records links the partners to other similar crimes.

Armed with enough evidence to pick up Randolph, he tells all on his partner in crime. Details and confessions pour forth. Where is the missing partner? Can the cops catch him before he leaves the country?

Orson is back to close the case and share the fates of the pair of killers.
