For an integer q, let chi be a primitive multiplicative character mod q. For integer a coprime to q, we obtain a bound of the form vertical bar Sigma(n <= N) Lambda(n)chi(n + a)vertical bar <= N/q(delta), N >= q(3/4+epsilon), where Lambda(n) is the von Mangoldt function. This improves on a series of previous results.
