A message to the devil

"You didn't?" Shera was intrigued. 

Alexa looked depressed. "Is there anyone who would love to be an assassin?" 

Shera raised an eyebrow and glanced at her. 

"I was pressured to do this, okay?" Alexa let out an exhausted sigh. "I already told you, I didn't even want to murder you in first place; or else I would have used an actual poisonous drug on you. But I didn't want to hurt you, okay? That is why I used one that wouldn't cause you any actual harm." 

"Is that so?" Shera scoffed. 

"Yes, if you don't believe me, you can check my dagger as well. It is a fake dagger whose blade will retract as soon as pressure is exerted on it." Even though that was what she said, she did not reach for the said dagger since she knew that Shera would not waste her time checking it.
