OK. I've found something and I'm so close to my final result.
Here is my new mwe:

Code: Select all

\documentclass[a4paper]{book}
\usepackage{enumitem}

\usepackage[standard]{ntheorem}
\theoremstyle{margin}
\theorembodyfont{\normalfont}
\newtheorem{exercise}{}[chapter]

\begin{document}

\setcounter{exercise}{8}
\begin{exercise}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut purus elit, vestibulum ut, placerat ac, adipiscing vitae, felis. Curabitur dictum gravida mauris. Nam arcu libero, nonummy eget, consectetuer id, vulputate a, magna. Donec vehicula augue eu neque.
\end{exercise}

\begin{exercise}

\setcounter{exercise}{127}
\begin{exercise}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut purus elit, vestibulum ut, placerat ac, adipiscing vitae, felis. Curabitur dictum gravida mauris. Nam arcu libero, nonummy eget, consectetuer id, vulputate a, magna. Donec vehicula augue eu neque.

\end{enumerate}

\end{exercise}

\end{document}

Now, the only problem is that the first letter of the theorem text (the word "Lorem" in mwe) is not left-aligned with the rest of the paragraph.
Any help, please?
