"Yes, it's about the victims' ages." You say, looking intently at the email while biting your thumb nail. "It seems the victims age doubles and once it reaches 64 it's impossible to double it again, as finding a 128 year old in Manchester is impossible, therefore he halves it again to get to 32. This means that they are in some way linked so it's highly improbable that it's a number of criminals working independently. I must say it's quite extreme to kidnap a child as young as one." You wait a moment to process all this then decide that this isn't sufficient. "Watari, please link me up to the next police meeting in the Manchester city police station. I would very much like access to these notes left behind."
"Of course. I've just arrived at the building. The next meeting on the matter is tomorrow though." Watari says.
"That's fine. It's unlikely they know of any outside involvement on the case at the current time anyway." You reply.
"Okay L, I'm just outside the meeting. Would you like me to enter?" Watari says down the phone. You hold it gingerly by the top with a finger and thumb.
"Yes please Watari." You say. "Once your inside link me up directly on the computer. I would very much like to hear what they have to say."
"The meeting has just started." Watari says as he takes the laptop inside. You can see the police officers looking startled.
"Hello. I am L." You say, the voice filter will make it sound different to the police to hide your identity.
"Who?" A young police officer asks.
"You may or may not know me. It's of no concern regardless. I am very interested in these kidnappings, please, could you tell me everything you know on this particular case?" You say.
"O-o-of course!" An older one stammers. You can tell he has heard of you from his surprized and relieved expression. "All we know is the victims names, ages and genders. We are looking further into their personal details. The only evidence we've acquired is the letters and the last times the victims were seen. The culprit is highly active, each one is one week apart."
"Okay." You say slowly. "Please send me everything possible on the case and if you wouldn't mind I would like access to all the Manchester police records."
"Why would you want access to them?" The younger one who spoke before says.
"No particular reason at the moment however they may prove useful later in this case. Although I doubt this will take much time to solve. Goodbye." You disconnect immediately and wait for Watari's call.
"Why do you want access to the police records L?" Watari asks when he calls.
Why do you want access to the police records.
1) He may have been involved in another smaller case (Chapter 4)
2) The police have already caught the culprit and are looking for accomplices (Chapter 5)
