I always get a strange feeling with this setting Bodie in CI5 and Doyle a Police officer, like: this setting is right and the series with Doyle in CI5 is wrong! It's that believable to me, especially when it's so competently done as in "Heat Trace", that I hardly consider it as an AU. With their characters Bodie is more the CI5 man to me as Doyle is. Probably just me feeling this way, but as there are a number of stories with this setting it seems to be believable enough for some. I also like the distance the lads get this way.
