I'm really struggling for a few letters.
11ac Serially deceived wife's husband beside date - h_r_
3dn Thief following what you'd think she'd break - fl_ _
22ac Still see brigade in action around Ohio - _ideo_rab video grab but where does the v come from? Brigade is in it but Ohio is OH
20dn Usher is quiet and always under contract - s_eer I think sheer but steer is closer to usher
Any help will be much appreciated. Thanks in anticipation.
