Mac is wonderful and I could listen to her all day, but so many episodes with Nancy Grace, who is so disrespectful to any subject she is not educated on. Cringe.
Sheryl McCollum has IT! She is a generous host to her guest speakers and nails the emotions of her audience.
The title got my attention. Is there anything Mac can’t do? CSI, Director, HOF, Mother, Wife, Friend. I admire her and must read her new book.
I look forward to Sheryl’s new Zone 7 podcasts every week. They are always so interesting and her guest are great! Sheryl has such a great mind for solving cases comes up with angles and ideas no one else thinks of to solve cases. She has such a gift for seeing thru all the muck and getting to the nitty gritty and answers. Cant wait to read her new Book Swans Don’t Swim in the Sewer!!!! Pre Order your book NOW!!
I just love Sheryl’s tone and accent, along with most of her guests, though, Dr Priya’s voice is like nails on a chalkboard. Unfortunately I am totally unable to listen to these particular podcasts. Love your work Sheryl.
