Um Crime Por Dia

The novel 'Gideon's Day' was the first in the Gideon series by John Creasey (written under the pseudonym of J J Marric) and was published in 1955. Each book in the series followed 'G G' (George Gideon) through a period of time. Cases that came up during that time were not necessarily solved by the end of the novel: they were kind of a "slice of life" of (Creasey's image of) 50s Scotland Yard.

There are 21 novels in the Gideon series, as written by John Creasey, with the last one published in 1976 (2 years after his death). I did, however, once came across another Gideon novel, written after Creasey's death by another author using the name J J Marric. If you like the Gideon TV series and movie and are interested in the books, make SURE they are by Creasey as anything else is a very poor substitute.
