A collection $S = \{D_1,\ldots, D_n\}$ of divisors in a smooth variety $X$ isan {\em arrangement} if intersections of all subsets of $S$ are smooth. We showthat a double cover of $X$ ramified on an arrangement has a crepant resolutionunder additional hypotheses. Namely, we assume that all intersection componentsthat change the canonical divisor when blown up satisfy are {\em splayed}, aproperty of the tangent spaces of the components first studied by Faber. Thisstrengthens a result of Cynk and Hulek, which requires a stronger hypothesis onthe intersection components. Further, we study the singular subscheme of theunion of the divisors in $S$ and prove that it has a primary decompositionwhere the primary components are supported on exactly the subvarieties whichare blown up in the course of constructing the crepant resolution of the doublecover.
