Never play cards with Charlie Eppes. You will lose - not only at cards but at practically everything else, except perhaps golf. Numbers are his passion, he able to see permutations few others can, results startling and accurate.
FBI brother Don increasingly calls on his services, Charlie promptly to become immersed in equations and formulae to help steer LA cops onto the right track. Almost unerringly he pinpoints where the serial rapist lives and where he is next likely to strike, outwits computer hackers, anticipates the bank robbers' next port of call, traces the source of a killer flu virus, locates a railway saboteur - and much else besides.
Maths has been made interesting, which cannot often be said. The series owes more to cerebral activity than to action (although there is still quite a bit). The outcome may not appeal to those who prefer their cop shows jampacked with corrupt colleagues, mavericks, messy divorces, torrid romances, alcoholic excesses and other ploys to boost the ratings. Here the officers are competent, simply getting on with the job.
Strengths? An unusual premise (numbers the key to everything), a fine script, charismatic leads. Rob Morrow and David Krumholtz impress as Don and Charlie, their bond palpable and movingly depicted. Tactfully Don is coaxing Charlie out of an often reclusive existence. There, numbers have been his safety blanket when he is otherwise unable to cope - as throughout their mother's terminal illness. Family scenes with their dad (Judd Hirsch) generate a real warmth, they all in different ways getting on with life after their loss. For light relief Peter MacNicol stars as Charlie's former mentor, quirkily entertaining as he offers insight and occasionally urges caution to correct wobbles in the thought process.
Eleven episodes. Alas, no extras. Also alas, an over-abundance of music which often distracts - depriving the series of the five stars it would otherwise have received.
(Watch out for an in-joke. The film showing in one episode? "Sorry Wrong Number".)
