A fidelity tester does not provoke. She is not (always) hired by her wife. And she does not believe that all men cheat, although she has a 100 per cent success rate. Similar, however, are her colleagues who test disloyal women. In one of Warsaw’s restaurants, I met with the founder of the “Temida” detective agency, Marcin Miklaszewski, and a licensed detective and fidelity tester. Hear about stories of extreme disloyalty and… love.
