This walkthrough is freakin awful. It's more like a synopsis of the story. Doesn't help me solve cases at all.

The Quarter Moon Murders
It would seem that you might have just sent five innocent people to prison. The BD murder has sent you a number of clues to track him down for a final fight. Phelps will understand the first clue and send you to the Pershing Square.
Here will be the second clue. You can either drive around aimlessly and Phelps will announce the location after some time, or you can simply floor it to the Hall of Records.

At the hall of records, travel to the second floor and up another ladder to reach the top of the chandelier. walk carefully over the chains and you'll find the third clue. The chains will then break and you'll be forced to swing to safety.

With this new clue you can once again let Phelps sort things out over time or go right to the Public Library. Once there, climb up the pipes and over the scaffolding. You will want to walk very carefully as a misplaced step can lead to death. Once on top of the roof you'll gain the fourth clue.

With this clue your next destination is the Westlake Tar Pits. Suit up in the overalls on the docks and enter the tar. Align the camera so that you can always see the half-sunken dock and walk to the small island to the north. If you slip off the dock you'll be dead in the water. Once on the island you'll find the fifth clue.

This clue will lead you to the Art Museum. You'll need to enter a hedge maze, but the solution is very easy. Keep moving forward around the winding corners and you will soon come to an intersection: at each of these splits you have to go left, right, left, and right one more time to wind up in the center. The next clue rests here.

You'll now need to travel to the movie set back from your earlier Traffic Desk. Climb far up the stairs and the set will start to come apart. Balance on the broken pillar until Rusty clears a path. When this happens, smash into the newly deployed beam to land safely.
Quickly grab the last clue and escape the crumbling movie set before it's too late.

The final clue will lead you to the Abandoned Church. Here you will face the real killer of the last five murders: Garret Mason. Follow Mason down to the catacombs below and take cover to prevent being hit by his shotgun. Eventually you'll come to a single hallway where Mason will camp with his gun.
When this happens, pop out from your own cover and lay the law down with your six shooter. With Mason dead you'll finally complete the Homicide Desk.
