Reporter Norman C. Miller won a Pulitzer Prize in 1964 for his reporting on the De Angelis story.
Tino De Angelis was the ‘brains’ behind ‘The Great Salad Oil Swindle’ (the name of the book).
I have always found one of the most interesting ways of studying internal control systems and auditing procedures is by looking at reports on frauds, indicating where things have gone wrong in real life.
Last time I looked on Amazon there were some copies of one of my favourite books available, alternatively perhaps try your local library.
Happy bedtime reading!
