I love the show but really, how many dead bodies can a couple of landscapers happen to come across in a garden? In real life they'd be investigated as the prime suspects after the second body LOL
Gardeners might find more bodies than you could imagine.
In Canada there was a serial killer named Bruce McArthur, who was a landscaper, who hid his victims bodies in plant pots.
