The dialogue's sequence and line management could've been better tbh. It's so confusing when there's no indication of who's currently holding the line/is speaking. My advice, some people opt to leave the person's name behind every dialogue spoken BY elaborating the fine details of their body language/reaction anticipated or even what's happening to their surrounding. This will in turn creates a subtle separation between each dialogue as well as making the plot flows well. Just my 2 cent.
The prologue is interesting... telling about group of agents seemingly against each others. At least that what I could comprehend from this first chapter because the dialogue between characters are quite confusing tbh... Also there are some grammar issues, but I'm not here to judge since my story also couldn't escape from it. Regardless, this is still the very first chapters, I'm sure it will soon become better and better as your story continue. Keep writing
