Lestrade wasn't sure if Sherlock had ever said it directly to him. Probably, knowing him, but he couldn't recall.
What he could remember was the press release, where the phones of dozens of people lit up with one word. 'WRONG'
Wrong. Serial suicides did not have to be linked.
Wrong. The best people were not on the job.
Wrong. We are not all as safe as we want to be. (Granted, Lestrade knew that already, but damned if he was going to admit that to the press.)
And of course, he was right. Because Lestrade went to him after the next one showed up. Then the best people were on the job. And of course, he was right that serial suicides didn't have to be linked, mostly because they weren't serial suicides. They were serial killings, which completely changed the whole thing.
And as for the third one? No one could ever be as safe as they wanted to be, because there was and always would be crime.
Yet again, Sherlock was correct in telling Lestrade just how wrong he was.
Serial suicides that weren't. Suicides that weren't.
Could he be wrong again? Perhaps regarding Sherlock's death?
No, no, not possible.
But of course, he'd been wrong once before.
And since he wasn't Sherlock Holmes, he certainly could be wrong again.
The thought had never made him so happy.
