Assassin's Promise!

In an underground room, many LoA recruiters were left speechless by a single candidate's ignorance. They were all staring at him, feeling at an extreme loss. This dumbass had already killed more than half the candidates! How?!

"Why don't you enlighten him since you seem to understand what the next test entails." The fake lawyer told the thief, resisting the urge to curse the oblivious one aloud. 

The thief could only awkwardly smile as he complied: "The Assassin's Promise is an extremely serious affair. It consists in informing one's target about their upcoming demise via a special letter. This is the actual Promise."

"Oh, I see, ever more letters! What about texting them? Wouldn't it do the same?" Josh carelessly replied. 

"No way! It wouldn't have the same impact, and it's a matter of honor! It's a tradition as old as the assassin profession itself!" The thief exclaimed heatedly.
