I have a few suggestions on shows to check out - other services may also carry these.Some only made it a season or two, others hung out for 6 or more seasons and I never heard of them. Many are detective shows and some comedies, but all worthy of checking out.
MOTIVE - the only show I know off who shows you in the beginning, two diverse people living different as can be lives and at the end of the opening scenes they print on the screen "Victim" and "Killer" after being introduced to them. The story lines and the detectives are all very good.
VEXED - a British short run (9 episodes) detective show with a male/female detective team that often enters the work world of the victim to learn of those who could be the killers.
HUSTLE - similar to Leverage except these grifters aren't stealing from the rich to give to the poor, they pocket from their cons. Smart story lines and very good characters, long run series.
QUICKDRAW - set place in the old US West, this seemingly improve group of towns-folk and their Harvard educated Sheriff have incredibly fun plots in a light hearted show, now in season two.
10 Items or less - starring the sheriff and mortician from Quickdraw, this earlier made show takes place in a family owned supermarket and their competition store across the street. Same off the cuff improv style makes this another fun show - it ran a few full seasons.
CRISIS - when the President's son and the elite children of Washington (and the power players from the world) suddenly have their kids stolen from a highly protected field trip - all the powers of the government come out to rescue these young hostages.
WAKING THE DEAD - this is a COLD CASE type show likely what Cold Case spun from - with deep intriguing stories, you will have you dective skills tested every episode.
WHITECHAPEL - follow a modern day Jack the Ripper as detectives try to find this elusive killer(s) a full three seasons.
PARADOX - sadly too short, this show has what could be Alien assistance sent to a high tech lab (usually in the form of photos) which a small specialist team often has only hours to figure out and prevent murders and mayhem from occurring. Only a handful off episodes, and just when you start to figure when digital photos, just glimpses and hints of incidents to come are coming from the series ends - sad, but worth a watch.
ZEN - a smart detective show, again British of an out-of -the-box thinker who is rough around the edges but breaks cases that are tough.
THE BRIDGE - this American made show, based on a foreign show showcases a bridge from US to Mexico and the detectives who co-operate to solve murders that fall into the short span between the two countries. Often bogged down with jurisdiction issues, getting the killers out-weighs dealing with the paperwork and politics.
INJUSTICE - with the bad guy from THE FOLLOWING starring as the detective who breaks the rules but gets the bad guy, this is a powerfully written show that is a good hour of TV.
Hope you check some/all these out - some very captivating watching here.
