There's been a murder in Terminal City, and TCPD needs your help.

To figure out whodunit, you need access to a command line.

  • Open a Terminal, go to the location of the files (remember your cd command), and start by reading the file instructions.

    • One way you can do this is with the command:

      $ cat instructions
  1. To get started on how to use the command line, open or cheatsheet.pdf. Some easy ways to do this from the command line are to type:

    $ cat


    $ nano

    or even

    $ open
  2. Don't use a text editor to view any files except for these instructions, the cheetsheet, hints, or spec/solution_spec.rb.

  3. Once you think you have the solution, open up spec/solution_spec.rb and make the test pass by replacing the __ with your solution as a string.


If you do get stuck while trying to figure out who the murderer is, you can use the hints that have been provided for you! They are denoted with a filename called hint<number>. There are 8 hints total - simply replace <number> with a number 1 through 8. NOTE: try to do as much as you can without the hints!

To access a hint from the command line, simply type:

cat hint1


nano hint1


open hint1

Learn about Flatiron School's Mission

With a new take on education that falls somewhere between self-taught prodigy and four-year computer science degree, the Flatiron School promises to turn students with little programming experience into developers.

In the six months since the Manhattan coding school was acquired by WeWork, it has spawned locations in Washington, D.C., Brooklyn, and London. Now, WeWork is opening a fourth Flatiron School location, this time in Houston.

Adam Enbar, Flatiron School's cofounder, believes now is the time to grow. "How the world is changing has impacted working and learning in very similar ways. We think education fundamentally is about one thing: enabling people to pursue a better life."

Learn. Love. Code.
Students come to Flatiron School to change their lives. Join our driven community of career-changers and master the skills you need to become a software engineer or a data scientist.
