An excellent Rebus mystery: raking through the ashes of an Edinburgh hotel brings out all kinds of seamy connections between the business elite and Scotland’s criminal underworld, with Rebus and his colleagues bending rules slightly beyond my suspension of disbelief, but accepting the consequences when things go wrong. Rebus’ brother reappears as well. I worked out the significance of the gas being turned on before Rebus did, but there was a sufficiently satisfying series of twists before we reached the end. One of the better Rebuses I have read (of five so far).
