Thicker than Water

When young Walter finds a dead body along with the dead fish in his tutor's fishpond, he knows he should tell his old master, Charles Murray of Letho. The dead man leaves a pretty wife and child and a broken string quartet, but someone must have profited by his death - could it be the avenger from his past as his widow fears, or is it someone from closer at hand? St. Andrews is once again the setting for a murder mystery, and a puzzle that Murray must solve before themurderer strikes again.
