Lindsay wasn't disappointed.
While this matter was important, it was too naive to say that Luke would absolutely be able to solve the case.
Given his track record, this young man absolutely deserved the title of "master detective."
He had a 30% success rate with cracking major cases in NYPD, while it had been close to 40% in LAPD.
Generally, detectives would already be considered outstanding if they had a 10% success rate, while a 15 to 20% success rate was enough to earn them the title of "master detective."
It wasn't like the movies, where a person might only be considered a master detective if they solved 90 to 100% of their cases.
Say that a criminal killed someone but then died in a car accident without being discovered.
How could the case be solved? In any case, the person was already dead, and everything would come to an end, unless he left behind written evidence.
