I've also enjoyed Ivor's performances, mainly in this show where, as Inspector Large, he worked very well with Mike Pratt - another we lost far too soon. I haven't quite caught up with his similar role in The Saint because I've only reached the early stages of the second series, but am looking forward to his appearances very much. I remember Ivor mainly for his 'trademark' raised eyebrow, brought into use when he was suspicious of someone's remark much of the time!
