The Client List and Rizzoli & Isles star Colin Egglesfield will guest-star on Unforgettable next season, has learned exclusively.

Egglesfield will appear in the fifth episode of Season 3 as Charles Sewell, a hard-charging agent with the Coast Guard Investigative Services who helps Carrie (Poppy Montgomery) and Al (Dylan Walsh) in their investigation of a boat explosion in New York Harbor. And yes, sparks will fly — but not between who you're thinking. Charles and Al will have a bromance over their mutual love of boats, leaving Carrie hung out to dry, figuratively.
