What Was That ITV Drama Called?

Both Of These Were On ITV A While Ago I Cant Remember If It Was This Year Or Last ..But One Of Them Was 3 Parts About A Serial Killer Who Killed This First Woman Then This Other One And I Think Her Son Found Out But She'd Been Getting Stuff In The Post Like Knives That Cut Her Hand At One Point...It Turned Out His Son Knew The Guy Who Was The Murderer..He Looked Really Creepy I Cant Remember What He'd Been In Before..But In The End He Was Threatening Someone With A Gun At A Swimming Pool Or Something When He Got Arrested...
The Other One Was About This Woman Who Was Like Kidnapped By This Man Who Convinced Her That If She Ran Away People In White Vans Would Take Her Back [I Think He Was A Magician And A Plumber?] But She Was Going Out With This Guy Before Then For Some Reason He Started Texting His Daughter Who In The End He Tried To Kidnap Or Something Then He Put The First Woman In A Bath To Drown Her With The Lid On Top Of The Wood He Put Over The Bath But She Managed To Get Out Then RIght At The End She Stabbed Him! I Thought They Were Really Good But I Cant Remember What They Were Called...Thank You For Any Replies!

Was It Called The Roxy?

I have a tape of Postman Pat? Is this any help?

The latter is 'Marion Again' - i think..

Yeah the last one was Marion Again. It was filmed near me.
