For the Sauce:

Start to pan fired the butter with the Thyme and Pepper.
When the butter start bubbling add a ladle of Pasta Water and switch off the heat.

At this point we can cook the pasta in salty boiling water, when the pasta is half way cook (about 2 minutes) you can move it to the pan and mix it with the sauce. At this point you can turn off the heat and add some grate truffle and some grated parmesan.
