Up to his arrest two weeks later, Wallace made two voluntary statements but was never intensively questioned by the police although he was required to attend CID headquarters every day and was asked specific questions about whether the Wallaces had a maid, why he had asked the man who had taken the telephone message at the chess club to be specific about the time he took it, and whether he had spoken to anyone in the street on his way back to his house from his abortive attempt to find Mr. Qualtrough. The police had evidence that the telephone box used by "Qualtrough" to make his call to the chess club was situated just 400 yards from Wallace's home, although the person in the café who took the call was quite certain it was not Wallace on the other end of the line. Nevertheless, the police began to suspect that "Qualtrough" and Wallace were the same man. Wallace's legal team conducted timing tests that showed it was possible for someone to have made the call, catch a tram and arrive at the chess club when Wallace did, and it was equally possible for Wallace to arrive at the same time by boarding at the stop he claimed he had used, nowhere near the telephone box.
