Welcome to Detective Diaries, brought to you
by Private Detective's Answers investigation.
If you're captivated by the art of deduction,
the thrill of solving unsolvable, or the enigmatic world
of private investigation, you have just
found your new favorite podcast.

(00:24):
Detective Diaries are where secrets are unraveled,
and the truth is always a clue away.
Presented by Private Detective Answers in investigation.
Each episode contains of big conversations
about the real people involved in investigation.
Welcome to another episode of the Detective Diaries

(00:53):
with me, Harry Watts.
Today, I'm in Naples, Italy, and I'm
very thankful to be joined by Nigel Parsons, an experienced
investigator with decades of experience in the film.
So Nigel, what brings you to Naples today?
That's actually quite a hard one.
I want to be a base about this, but we are working for a crime.

(01:17):
And I can't actually talk about it,
but I can talk about anything else.
Well, I can understand the nature of the business.
So tell me then about some history, perhaps, because there's
obviously quite a lot of related aspects here,
this week.
Oh, no, you push my buttons.
I mean, I have a fascination with history,
and a fascination with detectives and investigators,

(01:42):
but not just detectives and investigators,
but those guys who play in the air things,
those guys who form the basis of what we do today.
I talk about Italy.
I talk about Italy's most famous detective,

(02:03):
was a wonderful chap, a totally romantic, called Giuseppe
Dorsi, and a apologise to anybody Italian,
including a colleague of mine who speaks fluent Italian,
who will probably assassinate my pronunciation.
But Giuseppe Dorsi is deemed to be Italy's greatest

(02:24):
detective.
He was born in 1891, and after the Walter career
on stage became a detective.
Dorsi was celebrated as a master of disguise, which
just conjures up all those romantic images.
In his course of his work, he changed his dress, his voice,

(02:47):
his mannerisms, and even his gender on occasions,
two infiltrate from all gangs.
I mean, some of his famous impersonations
were as a priest, as a general doctor,
as a truly Galician banker, and most famous thing,
and this is something I love as a check World War I,

(03:09):
that World War I veteran with a limp.
Can you hear me?
Can you hear me?
Is anybody there?
I'm Harry Watts.
I'm an audio technician and a private investigator.

(03:31):
Hear me on Detective Diaries, telling you about enhancing
poor quality audio recordings to make them clear and audible.
There must be multi-sue disguises from what I've understood.

(03:53):
But can you tell me more about the war veteran,
the check World veteran, disguised?
Yeah, but before getting to that,
Dorsi, his skills became known as, again,
apologies from my pronunciation, but a foggle,
this small detective he stole after the act
of the Apoglyphagoly who was adept at changing

(04:15):
his appearance on stage, often appearing
as multiple characters.
That check World veteran disguise.
I mean, it was just incredible.
It's stuff from story books.
He disguised himself as a check World veteran.
O minus Italian, as a check World veteran, with a limp,

(04:36):
and a limp was a big thing.
It all involved the demise of a chat named Gabriella Denoncio,
who was arrived on to Mussolini, by minuses in 1920s,
and the rise of Mussolini's right wing party in Italy.
And Denoncio was one of Mussolini's right rivals

(04:59):
to become dictator.
And Mussolini, of course, was later in 1922,
with March into the room with its black shirts
to become prime minister.
But Denoncio fell from the window.
And died.
Dolce, coming back to our detective, Giuseppe Dolce,
did not believe it was an accident.

(05:22):
And in the course of his investigation,
disguised as this check World veteran with a limp,
so nobody knew it was him.
He discovered that Denoncio was pushed.
Get involved.

(06:03):
It sounds like the beginnings of the summer blockbuster
hit.
I mean, was there any political intrigue to this at all?
Well, one would think so, but no.
Do you discover that Denoncio was pushed by his former mistress?

(06:26):
When it was discovered that the limping check World veteran
was an undercover detective, he was called a dirty cop.
Was he really a dirty cop?
Oh, far from it.
He was a man of absolute integrity.
Mussolini himself saw him as a hero, especially when in 1925,

(06:48):
he foiled an assassination plot on Mussolini himself.
So what actually happens is I see half that that?
He fell from growth in 1927, quite a sad demise,
and very, very much connected with the political turmoil
of the 1920s and Italy and establishment of Mussolini.

(07:11):
You know Mussolini who had praised him just a couple of years
earlier stabbed him in the back, metaphorically.
There were series of dreadful chalepops and murders in Rome.
The authorities who were getting pressure
because Mussolini's party was all involved in pushing

(07:36):
the sense of justice and producing crime
and the enumacety into going on there to the end of time.
Mussolini's party were pushing the authorities.
So the authorities, police authorities,
they just set this chap up.
Girolamini, his name was.
He was not guilty, but suddenly, after,

(07:58):
I think it was seven-child murders and rapes.
Girolamini was invested and absolutely pedigree,
pedigree, by the press.
Ilsi got this into his head, investigated very quietly
because he was told he couldn't do, proved him innocent,

(08:21):
unexposed, massive corruption within the police forces.
Hi, I'm Torva Copeman, and I'm the head of UK fingerprint.
We take your fingerprints for police clearances overseas
and other licenses.
You can listen to my podcast and all the services we provide here

(08:42):
on Detective Diaries.
In response, because politically, this was not the thing to do,
Dosi himself was arrested, he was jailed,
and then he was sent to a psychiatric hospital
where he spent the next 70 months.

(09:03):
So he's had this career being as a professional detective,
a pioneer of multiple disguises,
and then has this full of grace.
I mean, what happens to him in this warden in his later life?
He slipped into a demise, and then the years went by,
musting was the power of officers, as we all know.

(09:25):
Italy fell under fascist rule, and then the Allies
liberated Rome, liberated Paris,
in 1943 with tremendous stuff going on there.
I mean, they were sitting in this moment to hell.
In 1944, with the Allies in occupation,

(09:46):
they appointed Dosi as a special investigator.
And after that in 1946, he'd be joining the police,
and this time as director at the Central Office
of International Police.
His reputation, his integrity, were things
sort of lauded by the Allies,
and they could see the whole operation being in safe hands,

(10:08):
given of the massive corruption
that had been the previous 20 years.
I mean, Dosi retired in 1956, he lived a long life.
He died in 1981, 90 years old,
wrote his memoirs before that.
But yeah, here we are, in Italy.
Amazing.
It sounds like a complete highs and lows of Dosi's life.

(10:32):
But so thank you for that, Nigel.
That's wonderful.
And hopefully we'll be hearing some more about
potentially famous Tecriptives in other locations.
