  In this paper we show that the maximum number of hyperedges in a $3$-uniform
hypergraph on $n$ vertices without a (Berge) cycle of length five is less than
$(0.254 + o(1))n^{3/2}$, improving an estimate of Bollob\'as and Gy\H{o}ri.
  We obtain this result by showing that not many $3$-paths can start from
certain subgraphs of the shadow.
