I had been busy flirting with the owner of the new antique shop, hoping he would give me the address of a secret auction house. However, the longer he refused to share this information, the more obsessed with him I became.

Through stealthy detective work, I discovered he had a fondness for extreme sports and was a participant in a new weekend event in trendy Shoreditch. I arrived at the starting point in time to see my man, clad in Lycra and a crash helmet, lying prone on a trolley being pushed through a small hole in a front door. I asked another spectator what was going on. This was the first ever Shoreditch Dachshund Challenge, where participants attempted to squeeze through as many tiny Dachshund doggie doors as possible in an hour.
