Case Unclosed: The Tales Of Detective Lyra
The Case of the Empty Water Tank
Lyra Zhao-Fan furrows her brow in concentration. Their entire water supply lost to stupidity and lack of discipline. 4 suspects, each of them a trusted member of her retinue, with no clear proof of which one of them was responsible. What a conundrum this trip turned out to be. As Lyra racks her brain in order to figure out who the culprit is, she suddenly hears a sound of violin and feels a wave of inspiration come over her.
"Lyra, are you ok?" Cado Zhao-Fan asks of his wife, as he sees her suddenly go rigid. "We can just continue on our way. This is not your fault and the nearest settlement is close by. We can acquire supplies and fix the water tank there. It is not imperative for you to try to figure out who is responsible. We both know that inquisitive actions aren't our strong suits.
"Pish-posh, my good fellow. I could never leave a mystery like this just lying around. Do not be an imbecile and come on, Dr. Fan, we have a case to solve," Lyra suddenly declares, turning around sharply, brandishing an old fashioned pipe, which Cado could swear he has never seen or felt on her, especially after last night's thorough make-up-sex session and hasty rise from their bed this morning.
"Lyra, what are you…Where did you..?" Cado tries to ask, confused. And why did the skin below his nose suddenly itch so much?
"Dr. Fan, what did I just tell you about being an imbecile?" Lyra asks, exasperated, as she dons her ear-flapped travelling cap.
"…To not be, Ma'am," Cado answers.
"Excellent, you're learning. Now, stop wasting your time with trivialities and follow me, we have a lot to do before I can solve this case," Lyra declares, delighted, as she starts heading away.
"Of course, Mrs. Zhao-Fan, but where are we going?" Cado asks while running a finger over his neatly trimmed mustache.
"Why, to the crime scene, of course," Lyra calls back to him.
-Red Sun pilgrimage caravan; the supply van, 8:47 AM-
"The victim is a near 300 gallon opaque water tank. Due to the surprise Grimmsblood-outbrake, lot of the water was used to either to take care of the sick, or left to them so that they can survive until the next caravan picks them up after the worst of the outbreak was over and the pilgrimage caravan continued on its journey. Due to this decrease in the caravan's water supply, a water rationing was established. Apparently, this ration was not enough for someone and they decided to drink more from small hole in the tank, drilled near the bottom and back, using a cork stopper to fill the whole to stop it from leaking.
Due to these circumstances, it is safe to assume that the hole was drilled between last night and the caravan leaving the infected, though most likely the hole is rather recent due to the dehydration starting to take its toll on the retinue, making them do a stupid decision. Also, the cork itself didn't come off until last night, since the lack of water wasn't noticed until today. Also, due to the low amount of water in the tank there wasn't much spillage, meaning the cork could have gone off at any point of time during the night, since there wasn't enough of it left in the tank to spill everywhere on the van's floor, which would have alerted the person on guard duty. And speaking of the guards, the tank is guarded every night by member of the retinue and there's one guard shift during the night," Lyra summarizes, taking a breath from her pipe, which quickly led into loud coughing.
"Aha, so the culprit is obviously one of the guards on duty that night!" Cado denotes triumphantly.
"Wrong. We cannot denounce the possibility that the culprit decided to take a drink two nights ago or earlier, and that it was the rattling of the van during driving that made the cork fall off, not the culprit putting it back improperly. It is also possible that the culprit drank from the tank during the day, morning or evening, though these are less likely possibilities," Lyra admonishes Cado, getting her coughing under control.
"Then could it have been possible that an outside party or a stowaway could have done it, Mrs. Zhao-Fan?" Cado asks.
"No. Since the caravan is so small, it would be impossible for the stowaway to stay hidden, and due to us being in an inhospitable desert with roaming grimm, it is very unlikely and infeasible that there would be brigands or wanderers lurking near the caravan, Dr. Fan," Lyra answers.
"Hmm, true, true. So, how will we figure out the culprit, Mrs. Zhao-Fan?" Cado contemplates.
"That's easy, Dr. Fan: through deduction and logic. After studying the crime scene and the victim one more time, we will need to interrogate the suspects.
-Red Sun pilgrimage caravan; outside of a tent reserved for interrogations, 9:50 AM-
"We have four suspects in this case, all of them suffering from differing effects of dehydration. The first one is Carlos, who is suffering from mild headaches. He was one of the two people on guard duty last night. He was also the one who first noticed that the water tank was empty and informed others of it, which nearly lead into a brawl after people started suspecting each other," Lyra starts listing while taking another long breath from her pipe, this time keeping her coughing mostly under control.
"Wouldn't that mean that at least he is innocent, since he was the one who brought up the fact that the tank is empty?" Cado brings up.
"Of course not, Dr. Fan, do not be foolish. It is entirely possible that he did that in order to push suspicion away from himself and point it towards others. And besides, it is easy to pretend to have headaches.
Now, to continue, the second suspect is Mikael, who has been moving stiffly and sleeping more recently. He was on guard duty two nights ago. A strong case for his innocence, but not definitive.
The third suspect is Bethany, who has been suffering from emotional imbalance, which has led to crying. The important thing to note is that while she has been crying, there have been no tears. She was on guard duty two nights ago, on the same night with Mikael," Lyra continues.
"Could her emotional imbalance lead her to breaking the rationing?" Cado intersects.
"Possible. Good to see you using your head, Dr. Fan," Lyra congratulates him.
"Now, the last suspect is Anders, who has not been sweating despite the desert heat. While a strong indicator for a lack of water to sweat, he was on guard duty last night," Lyra finishes her list of subjects.
"Now, before I go through interrogating them," Lyra says, turning to face Cado and brandishing her pipe:
"Who do you think is the culprit?"
Hopefully I didn't completely butcher this. Most of my Sherlock Holmes knowledge come from Hound of Baskerville-movie, crossovers, cultural osmosis and Sherlock Hound.
