 FACT: When Emma is looking through suspect sketches at New Scotland  Yard with the two detectives, the female detective says that the  suspect is known by many different names, including "Louie" (or  "Louis") "Guanella". Emmas response is "Of course... all names of  Catholic saints." In the case of "Louie Guanella", this is  incorrect. Luigi Guanella was a Catholic priest from Northern Italy,  born in 1842 and died in 1912. Guanella was beatified in 1964 but  has NOT yet been canonized (made a saint) by the Roman Catholic  Church. He is therefore referred to as Blessed Luigi Guanella, not  Saint (Luigi) Guanella.
