Jeffrey returns with a combination of two of his specialties - add a letter and fun puns. "F" is the added letter, but he really goes out there to get his sound-alike puns. Every one of the sound words is changed when the "F is added but retain the same sound. Consistent as all of his work. 58 squares of theme fill, aided by four cheater squares, still left room for CULPRIT, HAPLESS, STACK UP, SYNDICS, ANOTHER'S and PURE EVIL. To solve one needs to open one's mind and close one's eyes to "hear" what he is saying. I loved FLORAL AND HARDY and BAGELS AND FLOCKS. YMMV let's see what he created.
