To the naïve or gullible, prisoner Derek Wood might seem an intriguing Renaissance man, based on a new, aggrandizing self-portrait. Twenty-five years ago, he shot three McDonald’s restaurant workers in the head in a bungled robbery-turned-multiple-murder in Nova Scotia. Wood is 44 and still behind bars in Quebec and now says he loves great Baroque composers of the 17th century. He invokes famed physicist Erwin Schrodinger. Wood insists he’s “funny” and a “bibliophile” with a “fondness for recondite words.” Really, he may simply be a remorseless killer who concocted a more likeable – and less threatening – persona, given his eligibility in September to seek full parole.
