Arrow: The Dark Archer Strikes Dubiski Solving the mystery at the core of Dubiski: Who is the Dark Archer?

The scene Starling City has problems. A masked vigilante, known to the Police as The Hood is cleaning up corruption in the city.

There is a new threat to both Starling City and The Hood (Green Arrow). Another arrow wielding vigilante is on the loose.

As you come into school one morning, you see Starling City police all over the school.

As you head into your physics class, you step around crime scene tape, and see the outline of a body on the floor.

A detective walks into the room and says, “I understand you are learning physics. That’s good enough. We’ve got our hands full with one vigilante. You’re going to help us find the other.”

After a stunned few seconds of silence, the detective continues, “There has been a crime committed in this school… a murder. We have been able to develop a list of suspects based on who was in the building. We have also obtained a list of the weapons which were available in the building.”

“The weapon involved was either a bow, or a crossbow. For each weapon, the arrow leaves at a verified speed, which will be provided for you shortly, along with a list of the suspects.

There were two arrows fired. While one was found in the body, the other missed and left an impact mark. We have also been able to determine the range of this arrow shot.

“You have two weeks to give us the combination of shooter and weapon,” she said. Then she turned on a heel and strode from the room.
