And then had come the unlooked-for tidings of the imminent proceedings for divorce. And such a divorce! There were cross-suits and allegations and counter-allegations, charges of cruelty and desertion, everything in fact that was necessary to make the case one of the most complicated and sensational of its kind.
What does "cross-suits" and "of its kind" mean? I found "cross" and "suit", but I couldn't find "cross-suits". I don't understand the role of "of its kind" in this sentence.
