Ioan Gruffud Ioan Gruffud

Having an immortal on the case is especially helpful when solving copycat murders it seems.

When a human heart is delivered to homicide on Tuesday's all-new Forever, Henry (Ioan Gruffudd) is the first to realize that they're on the trail of a Jack the Ripper copycat. His keen deduction might have something to do with the fact he was actually on-hand for the original murders (complete with a time period-appropriate mustache, mind you).
