Casebook Episode 3: Snake in the Grass is the third in a series of 3 first-person detective games using FMV, and follows after the previous game, Casebook Episode 2: The Watcher. In this game, you investigate the death of a man in a small town church.

Overview

In each game location, your notebook will prompt you to answer a series of questions. You must search the location and take photographs of pieces of evidence, then return to the van to analyze them. In analyzing the evidence, you will play a series of minigames. The lists in bold below are of the items that you need to photograph to solve each notebook objective. Optional items to photograph for extra points are not listed.

Chapel

Photograph the blood for analysis

  • Blood stain, on the floor next to #1 (Marcue's DNA)
  • Blood spatter, on the wall just above #1 (Marcue's DNA)
  • Blood spatter, on the wall beneath the first stained glass window (Marcue's DNA)
  • Blood stain, on the floor between the carpet segments (Marcue's DNA)
  • Blood stain, on the carpet next to #3 (Marcue's DNA)
  • Bloody vase, on the carpet next to #3 (Marcue's DNA)

Store all of the evidence in the folder. There is nothing to link yet.

Identify the murder weapon

  • Bell, on the floor near #3
  • Silver cup, on the floor near the altar
  • Silver cup, on the floor near the altar
  • Balustrade, on the left at #2

  • Watering equipment, on left bench (Hapman's prints)
  • Water supply map, on far end of left wall
  • Dynamite, wooden box on floor at far end of shed
  • Diagrams, on bench at far end of shed
  • List, beneath middle bench

Store this new evidence in the folder. Link the list and chemical notes. Now click on the pink sticky note, and click on the circled area at the top right of the map. After the cutscene, store the new evidence, then link the strange device with the watering equipment. Click on the yellow sticky note and reconstruct the strange device. After another cutscene, store the new evidence, then click on the yellow sticky note. Select the trapdoor to the right of the organ.

Laboratory

Find the chemicals

  • Chemicals, in dark bottle on top of blue drum near the stairs (formaldehyde)
  • White crystals, on balance scale on back wall (potassium butoxide)
  • Chemicals, large bottle containing dark liquid, left of balance scale (phenylpropanol)
  • Chemicals, in dark bottle on middle of shelf on back wall (formaldehyde)
  • Chemicals, in small brown plastic bottle on left of shelf on back wall (carbonic acid)
  • Chemicals, in dark bottle on top of blue drum near the window (formaldehyde)
  • White powder, on a sack beneath the window (sodium borohydride)

Click on the yellow sticky note and recreate the chemical to solve the case. In this segment, just try various orders of the 6 chemicals - when you get some correct, they will be identified for you in the list, and you can gradually work out the correct order.
