"That seems like a problem we could solve some other way. Why are there assassins after your family."

"Grandpa pissed off the mafia."

"Would Oahkar law enforcement do anything about this if mailed extraordinarily convincing evidence."

"Probably not."

"What's the rest of your family doing -"

"I don't know all of their strategies."

"Do you want to be a gardener or is it just slightly better than being dead."

"I like gardening. Probably would get sick of it if I had to do it twelve hours a day but there's that money thing here so I'm only doing six."

"If the mafia finds you here after all is anyone else going to get hurt?"

"The assassins are snipers, not bombers. I guess they could miss but they could miss anywhere."

"If you know who I'd be looking for I could keep an eye out."

"...what, like their names? I don't know their names."

"That is not the only conceivable kind of identifying information but it would be easiest. Names of the people sending them? Places they've recently been? People they've previously murdered?"

"Got my mom."

"I can check for 'em every morning, arrest them if they show."

"I don't know if it'd be the exact same assassin."

"I can check for more people but I'd need some way to pick them out."

"All I've got is 'assassins working for the mafia'."

"I'll read the one guy's email and see if I get anywhere."

"I don't think they're going to find me here unless you tell somebody."

"I'm not going to do that."

"Thanks."

He leaves. 

Follows up with a boyfriend the next day. "This gardener told me the mafia's trying to kill him, killed his mother. Think we can get some names from that?"

"Uh, I can get whoever killed his mom, but 'in the mafia' isn't a conjurable parameter."

"Yeah, I know, I want to read mom-killer's emails and see if there's anything."
