After Leonard accepted the invitation to join Wesley to investigate the crime scene, the latter wasn't finished.
"Does Miss Caroline also wish to join us?" Wesley gazed at the sitting Caroline.
"Your expertise would be well appreciated in the case that the crime scene had been altered or modified."
Given that the crime scene happened under the nose of the Merchant Guild, especially with many patrol guards. Wesley couldn't help but shake off the feelings that the culprit could still be in the guild and was possibly lying low amongst them.
Moreover, there was still the absent bodyguard whom Leonard had previously slapped away.
If the time of death matched precisely with the bodyguard's absence, then Wesley wouldn't be polite anymore.
To dare to commit a murder under his very authority was a slap in the face.
If news got out, then he would have lost all his prestige in one night.
