I've been reading through the Malbim Esther and have found it fascinating reading, and I was wondering whether there are any other notable seforim with divrei Torah about Purim. I am going through the Pachad Yitzchok on Purim, and I was wondering whether there are any other notable recommended sforim. Thanks!
There is a Sefer called Otzros HaTorah - Purim that is a Likut of many interesting and notable Divrei Torah. It is available on Purim as well as all the other Yomim Tovim.
