Mr. Ballin

And at first, the doctors there, including Dr. Jukes, thought this man and woman were just regular civilians who had gotten sick, maybe from an overdose.

But soon it became clear that both of those things were not true.

Number one, they were not just regular civilians.

The older man was a Russian spy who had defected to England.

And the young woman was his daughter.

And they had definitely not overdosed.

They had been poisoned.

An investigation discovered that the substance that had been used to poison them was this very rare and deadly chemical weapon created by Russia called Novichok, a kind of nerve agent.

And so three and a half months later, after Don and Charlie were hospitalized and getting worse and worse, and then that lab tech rushed down the hallway to show Dr. Jukes their new lab results,

It was Novichok, the deadly chemical that Dr. Jukes saw printed on the paper.

That was in their system.

Investigators in the spy poisoning case had never been able to figure out exactly how the poison had been administered to the spy and his daughter.

But the item that Murphy's forensics team had found on the counter in Charlie's apartment, the one that kind of stood out and didn't really appear like it belonged in the space...

was the item that ultimately solved that mystery.

It would turn out, Charlie actually found the source of the poison.

Unintentionally.

It was that brand new bottle of perfume that he had given to Dawn on the morning they both got sick.

because Charlie hadn't actually bought this gift at a store.

He couldn't have afforded it.

Instead, he had found it in a dumpster during one of his many dumpster diving excursions.
