Walking tours explore intriguing surroundings at a leisurely pace, much like a photography class held in a thick bog of quicksand. Let it all sink in with today's Groupon: for $26, you get a 90-minute Murder, Mystery & Mayhem walking tour for two people from Tour Guys Vancouver (a $52 value). Tours run through October 31 and take place on Friday, Saturday, and Sunday evenings at 7 p.m. and 9 p.m. Additional dates may be added.

Tour Guys' crew of local historians, pulp culture experts, and architecture gurus guide nocturnal sightseers on walking tours to discover sites of unsolved murders and sinister events. Tours kick off at Centennial Fountain in front of the Vancouver Gallery, where an expert raconteur brings life to the tale of the building's ill-fated architect and a cursed drafting compass that couldn't draw a symmetrical circle. Couples stretch their toes under the night's sky as they journey to the scenes of uncontrollable riots and crimes committed by the city's most notorious gangsters. Meanwhile, offbeat stories add a dash of laughter to the evening's wicked events. Ninety-minute treks end in Gastown near the supposedly haunted Blood Alley, where walking duos can ask guides for directions or which brand of vacuum works best for busting ghosts. While there are no age restrictions for the Murder, Mystery & Mayhem walking tour, Tour Guys advises that it is best enjoyed by those ages 12 and up.
