As the number of episodes created before the writers' strike dwindles, all three CSI shows present new offerings this week.

Starting out the week on Monday at 10:00pm EST, CSI: Miami deals with a dangerous weapon in "Guerillas in the Mist":

When a rare and illegal machine gun "vaporizes" three weapons' smugglers, the CSIs must find the killer before the gun causes more deaths.

This is Carey Meyer's second turn in the director's chair for Miami, and his first episode was last season's "Bloodline". Barry O'Brien has written twelve previous episodes of Miami including "Permanent Vacation" from earlier this season. "Guerillas in the Mist" marks Brian Davidson's tenth episode as a writer for Miami. His previous credits include "Chain Reaction" from the current season.

The following actors and actresses are guest-starring in "Guerillas in the Mist":

• Boti Bliss as Maxine Valera

On Wednesday at 10:00pm EST, CSI: New York continues the week with "Child's Play", and one of the CSIs has a personal connection to a young victim:

When CSIs investigate a murder victim, the clues lead them to an infamous seller of killer pranks, "Laughing Larry." Meanwhile, Danny works on a case involving a boy from his neighborhood.

Jeffrey Hunt has directed two previous episodes of New York, including this season's "Buzzkill". Executive producer Pam Veasey has writing credit for 18 other episodes of New York, the latest being the season four premiere, "Can You Hear Me Now?" This is the second time that Trey Callaway has written for CSI: NY, and his other credit is for "Time's Up".

Thursday finds the CSI: Crime Scene Investigation team investigating the death of a rich woman while Warrick searches for the truth in "Laying Down with Dogs" at 9:00pm EST:

Grissom and his team delve into the world of illegal dog fighting to find out who is responsible for the death of a wealthy socialite. Meanwhile, Warrick tries to clear his name in the murder of an exotic dancer.
