Professor Thomas Howard is a retired archaeologist and grandfather of Pete.
Howard was an adventurer and risk taker in his youth, but had mellowed out a bit in his elder years. His goal was to find the Bronze of Bastet, an Ancient Egyptian dial, but after only finding one half, he eventually conceded that he would never find the other half until Dr. Philip Wellington revealed to him that he had the other half, which meant they could use it to unlock the hidden Cat's Eye. He cares deeply for his grandson, Pete, although tends to be more formal and less buddy by referring to him by his full name of "Peter." He shows his love for his old dog, Digger, by keeping his neckerchief and framing photos of him.
