THE MOTIVE, the latest installment in the excellent series of legal thrillers/police procedurals by John Lescroart, is an excellent sequel to the two previous stories in the series. THE FIRST LAW (review 2/9/2003) was a completely atypical story in the series — it involved an incident that would unavoidably alter the relationship of attorney Dismas (Diz) Hardy and Deputy Police Chief Abraham (Abe) Glitsky forever as well as create a significant inflection point in both of their lives and careers. THE SECOND CHAIR (review 4/22/2004) involves Hardy's initial attempts to regain his personal and professional balance in the wake of that incident. In that novel, Hardy agrees to act as second chair to one of his young associates who is tempted to engage in a plea bargain for her young client in view of the apparently overwhelming evidence which the SFPD has assembled.
